Was I wrong??

It might be stupid to some people, but Long story short, my boyfriend ( who is 25 ) and I like to play games to relax but it doesn't go too well when we play together because he gets really angry because of losing one or two games and it scares me and makes me sad. I'm talking trash talking people in game, calling them brain damaged, autistic

, swearing loudly, hitting table or anything that's near it. But everytime he plays just with his friends, he never gets angry like that for losing. I often join him and our close friend in a game so to me it's really embarassing when he gets so angry at me infront of friend. So I told him I'd rather not play with him anymore. We talk about it, he cries, promises he won't do it again, blah blah. Fast forward 2 days from the talk, here we go again. We played with his friend, lost one game and it was already enough for me so I just said goodbye to them and stopped playing. He doesn't even think he did anything wrong. I tried to explain my feelings to him but he just said I don't want to improve my game and that I'm not even trying. We usually live together but I'm away for a few days, he just left me on read. It makes me wonder if this is how much I mean to him, to not talk to me over a game.. These are the messages I sent.
