My boyfriend of 3 years is in love with another girl?

so i broke it off...i became all obsessed with this other guy for a few months and he fell back in love with this girl now im stuck livin with him and his fam til i find a job...i need a place to stay..i dont talk to my parents for abuse reasons...no one's helping me...i also suffer from social anxiety and it's really hard knowing someone wont be there with u along the way to help u.
