Feelings of Frustration

I love him but I feel he loves his bad habits more. When I try to encourage him to leave that past behind him, he feels I’m judging him I don’t know what to do anymore I feel like we are going in circles. I worry about him constantly that he’ll cheat and I hate when he feels sketchy and I hate when he pushes me away. I’m just tired but I feel such a strong connection it just really really hurts. Anyone have advice? I’ve tried talking to him but, it always feels like it fails.i don’t want to leave him but idk anymore
