After the end of a relationship, it can be difficult to cope with your ex moving on quickly. Seeing a new person with the one you loved (or still love) can be painful and make it difficult for you to move on from the relationship. When it happens, you may find yourself missing them. 

On the other hand, you might be feeling mixed emotions or be annoyed to see your ex appear happy when you haven’t moved on yet. These feelings might be challenging to understand initially, and you might be tempted to react negatively. But following your impulses might not help you feel good or gain a new perspective. Here are five areas to avoid when your ex moves on, plus tips for coping with the feelings that may arise. 

Why breakups are hard and five simple facts to remember 

Most people struggle with negative feelings after the loss of a relationship. Those feelings can re-emerge or worsen when one person moves on. For example, seeing your ex with a new love interest may reignite the original pain of the breakup — you might feel like pretty much everything reminds you of them.

Breakups rewrite daily life and can change your world, at least for a while. When we experience a loss like a major breakup, we may constantly feel grief and jealousy. But the simple fact is that these are not moral failings, but normal human reactions to loss.The following tips are a few strategies you might try to use your time and energy to support your healing process, boost your self-esteem, and prepare you for stronger relationships in the future. 

Relationships can end under unique circumstances, so not all the tips included may apply to your situation. Here are five things to avoid. Consider each tip and visualize how you might use it as a coping skill to cope with the end of your last relationship.

Thing 1: Don’t violate your ex’s space or stalk their social media 

After a recent breakup, past partners may experience various competing emotions. It can benefit both ex-partners to have time and space to process these emotions before making significant decisions. You may be more prone to react out of emotion when you’re constantlyexperiencing the pain of rejection, grief, or guilt. 

Unfollow your ex on social media to protect your emotional wellbeing and take you out of the way of temptation. Seeing your ex living their best life (and remember, most people use social media to portray only the best parts of themselves), can cause an increase in negative emotions.

Take a moment to think before you reach out to your ex. Is there any real reason you need to get in touch with the person who has already moved on after the relationship ended? Reaching out could open old wounds. Calling or texting your ex randomly could also make it look like you’re trying to get in between your ex and their new relationship. This behavior could cause challenges between you and your ex and the person your ex has moved on to date. Surround yourself with friends and give your ex space. 

Thing 2: Don’t ignore your instincts or idealize the past 

When a relationship ends, it can be normal to question whether it was the right decision. Try to avoid allowing your thoughts to enter a cycle of self-doubt after your ex has moved on. Often, when a relationship ends, it’s not a spur-of-the-moment decision. You may have invested time and energy into considering the pros and cons of maintaining the relationship. 

When mourning the loss of your relationship, it can be easy to imagine away all of the negative aspects, or to idealize your time together. It may be helpful to journal through some of these feelings to separate fact and fantasy.

Also, if your ex is with someone new, try not to allow this to affect your own thoughts in the present moment. Allow yourself time to accept the fact that the relationship has ended and to grieve the fact that your ex has moved on. If your instincts told you to end the relationship or that the relationship was unhealthy, trying to rekindle the connection may not be the best choice for your personal growth. 

Thing 3: Don’t get revenge

Seeking revenge is often considered unhealthy, as it may backfire or cause emotional or physical harm to you or your ex. It may not serve you in the ways that coping skills can.

When a person feels rejected or abandoned, they may want to lash out at whoever incited those feelings. You might feel like you hate your ex or want them to fail in their new relationship. However, it’s not in your best interest to interfere in their lives or sabotage any new relationships. In the end, getting revenge may cause more emotional distress. It can consume your thoughts and actions and steal time that could have been spent productively. 

People seeking vengeance are often those who haven’t moved on. Although it can be okay to not be over your ex, it can be an unhealthy thing to be overly focused on an ex-boyfriend or girlfriend instead of yourself. Consider taking time to care for yourself instead of thinking about how you can hurt your ex. Instead of moving against your ex and their new partner, consider the people and situations you want to move toward that make you feel energized, accepted, and loved.

Thing 4: Don’t ignore your emotional well-being, or pretend that everything is “fine”

Missing someone is normal, even after an unhealthy or fast breakup. It is in your best interest to seek support from your loved ones, rather than try to suffer through your feelings alone. By protecting your emotional well-being, you can keep from entering a downward spiral, and one of the most protective things you can do is lean on your community. Feel your feelings, but also try not to avoid your friends and family members who want to help. Go out for coffee, spill your feelings to your friends over brunch, and complain to your parents. 

Consider using practices like radical acceptance to accept that your relationship has ended, and your ex has moved on. Try not to entertain ideas of your ex coming back or leaving their new relationship for you. 

Thing 5: Don’t rush into a new rebound relationship, or interfere with your ex’s relationships

It can be best to avoid your ex’s new relationship and to manage your feelings discreetly. As difficult as it might be, try to stay focused on your own life instead of someone else’s. Even if your ex treated you poorly or you’re concerned about their new partner, try not to intervene. It may backfire or have consequences for your safety. Even if you don’t want someone to be hurt the way you were, consider whether you might have believed someone if they contacted you in the early stages of your relationship with your ex to warn you.

How to prioritize your healing journey after a breakup 

It can be understandable if you struggle to move on after your breakup. However, each person is unique, and how long they take to move forward can vary. Let yourself take the time you need to heal, whether that takes a few weeks to a few years. Find ways to live your life healthily without your ex in it. Getting to know yourself again and addressing your emotions may help you cope with losing someone you care about. Below are a few tips to get started. 

Face your grief

You may experience grief after the end of a relationship. Grief is a normal response to any loss, and something most human beings experience over the course of their lives. It’s normal to feel bad post-breakup, and you’re not alone. You may find that keeping a journal helps you release some of your emotions regarding how your ex has moved on. Seeking counseling may also be a way to talk to someone else about moving on from your ex and receive insight on how to handle your emotions.

Feel your emotions when your ex moves on

Painful emotions can often cause physical responses in the body. For example, fear or anxiety may cause a person to breathe quickly or have a fast heart rate. These responses can be your body’s way of maintaining balance while navigating physical and emotional changes. 

When you experience these feelings, pay attention. Stay focused on your actions and try not to focus on negativity. Take some slow, deep breaths and relax. If you feel the urge to cry, cry. However, try not to repress your emotions. Studies show that repressing emotions can worsen mental and physical health. Acknowledging and processing your feelings, even when you feel terrible, may help you make peace with your ex’s behavior.  

Take each day as it comes 

Even if your ex seems happy in their new relationship or without you, it doesn’t necessarily mean you don’t need more time. Everyone manages situations differently. Try not to be too hard on yourself about how long you need to cope. 

Take it one day at a time — set goals in the short term and long term. Visit a friend and plan dinner or social events to get out of the house. You can also consider investing in your dreams and interests that you may have previously ignored. 

Consider professional support after your ex moved on

No matter how “composed” you may be under normal circumstances, a breakup can be challenging to overcome alone. It can be frustrating to see your ex with someone else, and you may feel stuck. It may feel like you can’t stop imagining their new reality or checking their social media. Other times, you may feel like no one understands what you’re going through. In these cases, a therapist can be an empathetic, stable, and professional resource to help you cope with the feelings you’re experiencing. 

Do’s and Don’ts short list

If you are still unsure of what to do after a break up, remember that you don’t need an exact plan, and refer to this quick guide of do’s and don’ts: 

DO:

  • Focus on putting your own well-being first
  • Unfollow your ex on all social media platforms
  • Spend time with friends and family
  • Get regular exercise 
  • Prioritize sleep hygiene
  • Get outside when possible
  • Engage in preferred hobbies and activities

DON’T: 

  • Text or otherwise reach out to your ex
  • Isolate yourself from others
  • Idealize or fantasize about your past relationship
  • Consider revenge or sabotaging your ex
  • Rush into a rebound relationship

Counseling options 

While some individuals may be comfortable seeking in-person counseling, others may feel more comfortable seeking support through other means, like online therapy. Online platforms like BetterHelp offer options for individuals seeking support in coping with significant life changes, including relationship changes and breakups. 

NPR discusses the science of breakups and recovery and how it may affect the brain. One of their main highlights was from a study that found that reflecting on a recent breakup can aid in healing, including figuring out who you are as a single person. Therapy is a safe place for growth after a breakup. In addition, research has found that online therapy can reduce distress from isolation or loneliness. 

Internet-based counseling may also have alternative benefits. BetterHelp offers the following tools to supplement therapy appointments:

  • Online tools like journaling prompts and habit tracker
  • Weekly online group seminars
  • Asynchronous messaging to contact your therapist at any time

If you struggle to get ready and leave home for an appointment, online therapy with a therapist from BetterHelp can allow you to connect with your counselor anywhere you have a safe internet connection. 

Getting started with BetterHelp is simple:

  1. Take a short questionnaire. Answer a few quick questions about your goals, preferences, and the type of therapist you’d like to work with.
  2. Get matched quickly. In most cases, you can be matched with a licensed provider in as little as 48 hours.
  3. Start therapy on your terms. Schedule sessions by video, phone, or live chat, and join from anywhere you have an internet connection.

Finding the right therapist isn’t just important – it’s everything.

Takeaway

Losing an ex to a breakup and watching them move on can be challenging to cope with. Should your ex move on before you, it might feel like losing a best friend. Consider reaching out to a counselor or trying a few lifestyle changes. Try to give your ex space and avoid sending impulsive messages. If you need additional support, you can reach out to an online therapist at any time for further guidance.
