need advice :/

So, lately my boyfriend moved in with me because his mom kicked him out. I'm still in high school and he goes to college but he wants to drop out of college. And recently  he keeps saying that I don't love him and I wanna go and cheat on him and he's always talking bad about me behind my back. And he got me into some other things that I need to get away from. But he's the main source of it. So i feel like I need to remove him from my life but apart of me wants to keep him in my life. I need yalls opinions from people I don't know? If that makes sense?!
