Gamer bf/husband?

Anyone on here have a gamer bf/husband who gets extremely violent on the game?? My bf will curse out lil kids on the game if they start talking shit to him and it’ll be early in the morning. Me, I do curse sometimes but I try not to make it a daily habit for the sake of my child. On top of that I’m a religious/spiritual person and just feel all that hatred and negativity is just doing too much. I’ve tried talking to him about it but he’s the type that just has to get the last word and have the last say. I’m trying to build a positive home and teach my daughter the word and it’s hard when one person in the house “claims” to be a believer but does everything the wrong way. I’ve tried explaining it to him and he still doesn’t make a change I’m starting to feel like he needs somebody that wants to put up with all that. A grown, 29 year old man cursing lil kids out on a game. On top of that we have a son otw and I don’t want my son to be anything like his father. Idk what to do. Advice?
