what would you do?

My boyfriend DOES NOT talk to me or ask me about certain stuff, I find out the day of. I live in his house with his mom and family. (I help around the house, clean, babysit) My boyfriend starts cleaning our closet and i ask what his doing he says his moving stuff so that his MOMS dog can start staying in OUR room with the huge kennel. I’m super irritated because I don’t really want that dog in here (I have allergies) and he just tells his mom that her dog can stay in here. He is a super bad mommy’s boy (my boyfriend.) I love him dearly I just wish he would talk to me about these things.
