Broken up but still hung up one one thing

My (basically) ex lived with an ex gf who hit him. He eventually ended it with her. He also would love some of her Facebook posts.

With me however he didn’t want to live with me, stating that he would only ever live with family again ie a wife. He said he wouldn’t jump into anything with someone again. Also with me he wanted space and only some nights a week with me but he lived with her!

Also the relationship lasted around 2 1/2 years whereas ours was only 1 1/2 years. She used to abuse him but he gave up on me sooner?

Both of these things I had to beg for and never got. I only was met with anger and distance. I feel mostly relieved that it’s over but I’m caught up on these two points. It makes me feel like he loved her more or that their relationship was more valuable.

I have very low self worth and self esteem. I know I’ll have to mourn the relationship soon and maybe these two things are just distractions the way they distracted me from my relationship when I was in it. I still just need some peace. It’s making me feel so worthless and small.
