How do I approach past trust issues and being insecure with my current boyfriend?

Our past experiences do impact the way we view the world and interact with those around us. If enough experiences are attached with negative messages, they can become negative core beliefs about ourselves, or the world around us.

It can be helpful to think about the messaging associated with your past experiences, that may have contributed to what you call trust issues. It's natural to want to protect yourself from future emotional hardship, and at this point it sounds like it may be impacting your ability to forge a connection you want and deserve with your current boyfriend. 

Being honest about your past relationships and the ways that you feel you've been impacted are important to communicate to your boyfriend so that you can build a relationship build on trust, honesty, and support. Challenge yourself to evaluate your boyfriend objectively. Has he behaved in a way that would make a person suspicious or untrusting of his loyalty? What is the evidence to support this rumination or thought? Fear may be making you want to avoid the conversation, and so maybe test the waters a bit with something smaller or more inconsequential. Since i'm not sure how long you've been together, you may not have had the time to evaluate if he is a trustworthy individual. Start noticing how he responds to you and those around you. Does he get defensive when you ask questions calmly and respectfully, shut you or others down, or display any other red flags? If not, I would encourage you to give him a chance to show you he's worth trusting. Maybe the vulnerability required is less than the anxiety you're already experiencing.

If this sounds too overwhelming, it may be worth working with a therapist individually first to address feelings of insecurity and increasing your self esteem and positive self regard. This can ensure that you're moving through your relationship with a secure and balanced perspective where you're clear on what you bring to the relationship, what you get out of it, and how it enhances your life or not. Ideally, being in relationship with this person is in line with your goals and values, as that would likely have the best outcomes long term.

Hope this gives you some things to think about!
