I need help ASAP

I'm in a relationship for going on 5 months and we live together. I'm 17 and he's 22 I was having trouble at home so he let me move in with him and his mom. And now I regret it, I feel that I'll pick the abuse at home than this relationship. His a sweetheart sometimes but most his an ass wants to control everything I do!! He wants all my attention but don't give me his. I can't talk to in friends on the phone without him saying something about it. And I'm just unhappy, im done fighting and being with someone who don't seem like they want me only sex. He never called me out my name or put his hands on me but I don't put it pass him. His a different person from the beginning the totally opposite, and he don't wanna do anything with his life. But I've been talking to this guy the last couple of weeks and he seems to be everything I want. He knows I have a boyfriend so we don't do anything bad, but flirt here nd there. But he works, went to school to become a chef so he cooks and have plan in life. He makes me laugh and we been texting nonstop for the last two weeks. He talk about everything, I met him once and he was a totally a sweetheart but more quite than I thought but I like that about him. I would leave my boyfriend but his family the only family I have be I have no where else to go but outta state me I have a little sister back at my old house that I can't leave here alone. I need son girl advice cause my friends just see that he buys me things (but think he can control me after).
