Do I Stay Or Leave?

Me and my boyfriend have been together for a year and a half. We started long distance and then he moved in with me about 6 months in. In the last 6 or so months it’s been rocky for me personally. Lots of arguments, screaming matches and just feeling disappointed and disrespected on my end with what I’m receiving from him. I have ended our relationship one night and in the morning I basically felt bad and told him I still wanted to be with him. (I think this is mostly because without me, he has nowhere to go, he’d have to most likely quit his job he got out here and he’s also the type to do petty things from a breakup) . This is my second relationship, and my first one i eventually got myself to leave but I always knew it took me too long and i wasted so much valuable time holding onto a cheating man. That relationship I was harassed for months after I left and had to get a restraining order. So I guess I just have more fear with leaving than I do staying.
