Be honest ... RELATIONSHIP QUESTION

Are you suppose to be able to tell your SO anything and everything ? In my experience whenever I tell my SO something really deep or personal he uses it against me in a fight or to hurt me some how. Like for example I was involved in child sex trafficking and I am in recovery for over two years now for substance abuse. My SO knows this about me so every time we fight he says " I'm a whore , I sucked dick for money , I'm nasty , I'm nothing but a junkie etc." he never apologizes for it ...EVER . I've put up with it for 5 years now and I'm sick of it and for some reason it's really bothering me now to the point of me constantly crying and not wanting to be by him or him to touch me or anything . I catch myself blatantly going out of my way to be away from him. Idk I want honest answers bc nobody's relationship is perfect . So is this normal or what ? Also it seems like everyone I've ever known has done this to some degree ... so is this just normal ? I mean I'm honestly trying to figure this out or is it just me ?
