Questioning my relationship

My bf/bd was a piece of shit in the beginning of our relationship. Like, awful. Cheated, ruined my pregnancy, wasn’t there when I gave birth, went on tinder and used a pic of him posing in front of my car for it 😂, and many many other things. He’s changed now and all that was years ago, but I’m slowly losing attraction for him. Not just cause of the way he treated me, other reasons as well. I was 18 and he was 23 when we first got together. I got pregnant quick. I’m now 23 and he’s 27. The older I’ve got, the more I’ve noticed my type change. He’s nothing near it.

He’s a smoker, I’ve grown to hate smokers. He’s not good at communicating at all, and that’s something I adore in a man. His looks aren’t my cup of tea anymore either.

I’m just confused on whether I should take this to couples counseling to try an save it for my son. Or just end it. He used to be the problem. But now I feel I’m the problem. 😂
