Cat owners help

I’ve never owned a cat in fact I hate them but I got one a couple months ago bc my boyfriend won’t let me get a dog. Anyways he bites my baby trying to play, attacks her feet when she’s in her walker, takes her and only her clothing under the couch and chews it. He takes baths so a squirt bottle doesn’t bother him. I’m not a cat person and I’m on the edge😫 please help me any suggestions?
