Needing Help. A lot.

I've been in a situation for a few months now.

I met this guy through tinder and we really hit it off. We started talking more and eventually he started to stay with me.

We've been together a few months now but things have been rocky.

He gets really upset/irritated over really small things.

Im not allowed to have any guy friends at all.

He constantly asks where I'm at and what I'm doing and who I am with.

^He doesnt believe me when I tell him these things

Hes blown up at me because my brother doesn't like him and called him a bi*ch (my brother is 16 and very overprotective of me, I'm 19)

I feel like I need to get out.

I don't know how though..

Im afraid of being alone and im afraid of what his family might do.

I'm at a loss..
