In laws from hell

My boyfriend & I live with his parents. They are Italian and the most stubborn rude people I've ever met. I have a 9 month old daughter and they like to pretend they she is theirs. Constantly kissing her, tells me no when I want her back, & just tries to always but in when I parent.

My boyfriend and I have been arguing all the time because we just don't say anything to keep the peace until today I've finally had it. I made him tell his mom how we feel. I'm currently in my room here, shaking, so much anxiety because i just heard them get home and they are throwing stuff around and everything. I'm seriously terrified. I have no where else to go. Idk what to do.
