Is this okay ?

I was dating a guy for 6 months and we recently broke it off. But he says he doesn’t wanna be with me because I went out with my sister and friends and dressed skimpy. And he think I cheated on him or did some weird shit. But he still comes around me and has sex with me and acts as if we are together. Then he’ll get mad randomly and say “this is why we not together” then he’ll distance himself and stop touching me and kissing me. And I’ll cry. It genuinely hurts. I feel so lost I just want to let him go but I can’t. He tells me he doesn’t do anything with anybody and he’s focusing on himself. And he’ll tell me things like I make it hard for him to walk away and I make him feel bad. He’s confusing me!
