Need advise

So I have been with my boyfriend for a little under a year and we've known each other for six or seven years. We'll we recently relocated with his brother to a new date. And now all of a sudden I feel really really alone. Our whole relationship has changed I feel controlled I can't even pick up my phone with out him asking me who I'm talking to, and he freaked out about my shorts ect. Absolutely everything is in my name and I'm mostly paying for everything. To make matters worse anytime we get into a fight his brother gets all posse off and starts being extremely rude so I feel so alone and I'm afraid to tell my mom or friends cause I'm three stated away ad they'll tell me to come home. What do I do? I've tried talking to them and it made things worse.
