How do you deal and get over the resentment you have after a break up?
I recently got out of a toxic relationship where I feel that person hurt me deeply, both emotionally and physically, but above all, it's the psychological damage. The internal rage of having stayed despite the abuse has made me overthink and ruminate constantly, even now, two months after breaking up. After we split, I was given a heads-up that my ex had probably been talking to another girl while we were still together. I broke no-contact to demand an explanation, but he just told me 'I didn't do any of that' and ghosted me for good.
Now, he spends his time posting things about how 'you shouldn't stay with sick people' or how 'men just want peace in a relationship.' It's funny, because I actually did lose my mind in that relationship, but it's easy to point fingers at me and take zero responsibility for all the lies, an infidelity, the mistreatment, and the hidden things he did to me that ultimately shattered all my trust.
Now I feel like he got away scot-free, and worst of all, he will think 'he's the good guy' and believe his own narrative. Even so, I know this is consuming me and I don't want to keep living like this. I want to be happy and feel excited about things again. I moved to a new city alone for him, and it's being really hard to deal with both the loneliness and the breakup at the same time. I've realized that first, I need to let go of the resentment. I need to stop checking what he reposts, what he tweets...
It doesn't matter anymore whether I meant something in his life or not. I know I gave everything for him, I know I loved him from the bottom of my heart. I can feel proud of that, but I have to turn the page. Any advice on how to deal with the anger and resentment?
