Why do i want him to feel bad after our breakup?

He actually knows I feel hurt. He isn't right for me. He was okay with fumbling me, when he decided to end things. He clearly showed that he didn't care anymore.

I still hope that he'll apologise and I HATE that I think he'll feel empathy after all. I just want to feel justified and move on

A mutual (she's a good friend of mine, her bf is my ex's friend but he has said he's an idiot, he was also hurt by him in the past) said that he's the kind of person who comes back. I cant stop thinking about it...
