Boyfriend Advice!!! Please help!!!?

So my bf and I have been together for over a year now. His dad left him and his mom when he was a baby and he lives with his mom and her boyfriend Chad. My dad left me and my mom when I was younger and my mom died of cancer a few years ago so I can really relate to my bf. I live with my god parents and their daughter Teagan she the little sister I always wanted. Any way both of my god parents love my bf and really care about him. My bf's mom and chad have always been on drugs and my bf and chad always get into fights and most of the time my bf gets hurt. (by the way my bf's name is Mason) so my godparents Stacy and Mike have been asking me why mason always looks all beat up and always looks sad. so I told them and they said if its really that bad at home for him then he could move in with us bc we have enough room and they really trust him. the only thing is I don't want it to hurt are relationship we havent had yet but if he moves in i can see that happining in the near future. And i'm afraid if we would get into a horrible fight he would wanna move out and would have no where to go. whether we are boyfriend and girfriend or just friends i want him to move in so he can be in a happy and safe enviroment. please tell me what you think???
