Stressing out here😢

Ladies I need help!😩 So last night my bf got into it with his brother. Nd his brother started saying stuff to me also nd my bf got more mad. As for over 2 years I've been staying with my bf nd his sister nd her husband nd her kids nd lately their brother has been staying with us as well. With all this happened I just don't feel too comfortable there anymore nd now I'm thinking on leaving but I'm just so use to being with my better half... I haven't told him anything cause I'm still thinking but I just need advise...
