Confused?

My boyfriend and I live together, with roommates and 3 nights ago my boyfriend got mad at me because he had to basically move his game room into our bedroom, when he got off the game he came into bed with me and started crying saying that “he was sorry for getting mad at me” and “he’s scared that I will one day I will leave him because of things like this” and I said it was as okay but in my mind I really wasn’t..... anyways after that night he’s been doing nothing but putting me down and getting mad at me for every little thing (ex: when I watch tv in the room bc he can’t hear his game, or when I talk he gets annoyed) and I really don’t know what I do or what’s wrong? Please someone help.
