How to get over the feeling of wanting “revenge”?

Revenge, but not in the normal sense. We broke up 4 days ago and some things happened and he moved on rather quickly let’s just say. I have no idea if he actually cheated or not or it’s just a friend but anyways….

I obviously feel anger for everything he put me through in the relationship (I’m talking abuse) and then breaking up with ME, blaming me for everything, and then going with someone else.

I think I’m going through an ego death because I’m mad I wasn’t the one who broke it off and I’m mad about everything he put me through and me staying and putting up with abuse.

However, I don’t want revenge in the normal sense… I don’t want him to get hurt, nor do I personally want to do anything to him…, i just want him to feel bad about everything…I want him to care and need me and realize he fucked up, even though I cut off the contact and would never go back.

How do I get over this feeling? Especially for someone who literally put me through hell on earth? I want to stop caring in general about him.
