I was in a similar situation. (Sometimes the urge still hits me to look him up.) I kept hoping that despite all the signs he actually cared about me. Unfortunately what cured me was something that completely broke me.

However when I finally came to my senses I was finally able to accept not just that it was over but that he really was an abusive a*hole and that it hadn't all been my fault.

I really hope it doesn't come to that for you.

My therapist suggested this to me for other thoughts but maybe it could help you.

Essentially, wear a rubber band or something you can kind of snap to get your attention then when you have a thought about him you snap it and deliberately think of something else.

I'm still not entirely sure how it's supposed to work I'm guessing some sort of distraction thing, or maybe thought training/punishment. (Which I think is kinda weird but okay lol)
