how can I break this obsession?

I’ve been stalking my partner’s ex social media for over 8 months and I’m still doing it every day. I can’t stop doing it, I just want to know what is she up to and does she still remember him or still posts stuff about him

Dear Lavieenrose,
Thank you for your message and I am sorry to hear about your break up. Thank you for your courage in sharing with me your pain.

Closure is something everyone would like. We would like validation and understanding after a relationship has ended.
We can accept that someone doesn’t want to be with us. We can accept that the relationship has changed or that they want something else. What we can’t accept is our partner’s inability to communicate that fact effectively and tell us what went wrong.
Unfortunately, sometimes your partner does not have this same need, or they may have the same need but they’re better at hiding it and pretending they don’t. They would rather just push you, and their feelings, away.
In my experience, people can’t always be honest with you because they can’t be honest with themselves. It isn’t about you. We always want it to be about us and our flaws and failures, but it isn’t.
Many people don’t know how to deal with the emotions that come with a breakup, so they prefer to avoid their feelings altogether, and this is the most likely reason they won’t talk to you. It has nothing to do with you or the relationship or something you did wrong or that you weren’t enough.
I’ve dealt with trying to get closure a few times, and it’s awful. No one likes to be ignored, and no one likes to not get answers to their questions. But, what you have to learn is that any answer you get won’t change anything, and it may or may not be the truth anyway.
I can only control myself and my actions and how I deal with the ending of another relationship that I thought could mean something.
If people want to be in your life they make an effort. If they don’t, then you are better off without them.
If you are struggling with getting closure with an ex, ask yourself why you want to talk to them. Is it to get them back? Is it to get them to validate the relationship? Is it to try to get some type of reaction, or any type of reaction? 
If you are making up reasons why you need to talk to them, then perhaps you need to get closure from yourself. If they won’t talk to you, reaching out will likely cause you more pain and frustration. So instead, I suggest the following:
1. Write a letter.
Write one every day if you need to. Don’t send it; just get the feelings out there. You can write them here if you would like. :)
2. Write out reasons why they may be avoiding you that have nothing to do with you.
We all create explanations in our heads as to why our ex won’t talk to us. We imagine they think bad things about us, they don’t want us, that we weren’t enough, or that everything was our fault. Thoughts in your head are just your interpretation of what happened, and they are usually incorrect.
What if what they are really thinking is this? Do you think they are going to tell you?
I’m afraid to be open and be hurt again.
I don’t think I can give this person what they need.
Being vulnerable is too scary.
He/she is too good for me.
My abandonment issues have triggered my unconscious need to be alone.
3. Unless this was your first love, remember that you loved before and you got over it.
You control whether you move on. And you can decide if you want to wallow in self-pity and misery, or pick yourself up off the floor and be the spectacular, amazing person you are and get out there and show yourself to the world.
4. Take your feelings and write them on little pieces of paper.
“I am hurt.”
“I am angry.”
“I am sad.”
“I am devastated.”
“I am heartbroken.”
“I feel rejected.”
Get a fireproof bowl and fill it with some sand. Put all the little pieces of paper in the bowl and light them on fire. Watch the words burn and with them, let the feelings go.
5. Be alone.
Be still. Cry and be sad over the loss. Accept that what once was, is no longer, and what you thought would be will never be. If it’s meant to be in the future, it will find a way to work itself out. Maybe now is just not the time.
6. Live in abundance.
They are not the only person in the world. There are literally millions of single people in the world. If you had love before, you will have it again. Stop thinking that you’ll never find someone else so wonderful. If they were so wonderful they would still be with you. They aren’t. They’re gone.
What is it you are really hoping to hear? Do you think most people can admit their fears? Of course we all would like our partner to care enough to tell us the truth no matter how much it hurts.
There are a million reasons that relationships don’t work and tons of reasons why your ex won’t talk to you. Don’t take on their issues and make them your own. Realize that we all have insecurities, and not all of us can understand how they impact us.
I’m sure you would love for your ex to say, “You are truly amazing and wonderful, but I don’t think we are a match.” The reason most won’t say this is that they don’t want you to come back at them with all sorts of reasons why you are a match, so they’d rather avoid the topic altogether.
For whatever reason, your ex has chosen to cease all communication with you. The best thing you can do is take it as a sign from the universe that it’s time to move on, and that any person worthy of being your partner would never leave you in the lurch like that.
Remember this saying, “If not this, something better.” These words sound stupid and irritating when your relationship has just ended, but they are true for a reason.
We don’t’ always get what we want, but we get what we need. Change is inevitable. Change is good. If it was meant to be, it would have been, and if it is meant to be, it will be.
Unfortunately, life does not always go along with our pre-conceived notions of how things should be, and people aren’t always what we want and need them to be. Life isn’t always wrapped up in a pretty package with a bow on top.
Sometimes you get closure and sometimes you don’t. Sometimes the lack of closure is the very lesson that you needed to learn. Maybe you needed to learn to validate yourself and accept yourself.
Consider seeing this person as a gift sent to you. They were brought to you as a reflection of yourself. Thank them for being a part of your journey and send them on their way in your mind.
Lastly, if you are waiting for your ex to give you closure, it might be time to dig deep inside and give it to yourself.
Looking forward to talking with you more,
