I don't really know what kind of help I expect by asking this here, but since this is the 'off-topic' section of the forums, though still somewhat related to gaming...I'm gonna give it a shot. Perhaps there are other gaming couples that lurk on these forums and have some experience.
Anyway, my bf and I are both gamers and that's how we met each other (2 years ago). We've enjoyed playing many coop games together, and working on getting platinum for them. Once in awhile though, competitiveness strikes. It's seems that I'm never allowed to win for one thing, otherwise he becomes a downer and makes comments like "I suck at this game" etc. He said once that it makes him feel he is not good enough, or that he is stupid when he doesn't understand something but I do. I think it would be worse to not be myself and let him win. He accused me before of letting him win when I didn't, and he didn't believe me. In one game, he would go back after we were done playing, and intentionally try and beat my scores. I couldn't believe it bothered him so much. I used to be more competitive years ago, but nowadays I don't bother because I don't want to get into an argument or anything.
He also has this weird thing about getting revenge. He says if he saw me playing a game with other people, that he would intentionally play without me. It's Rock Band, not like a leveling up game or anything. I honestly wouldn't give a crap if he did, but I still don't because I don't want to argue. Because of this, I don't get to play with certain online friends anymore. Yesterday we were playing Rock Band and I unintentionally picked a song that was difficult (he has a 97% on it though so I assumed he could handle it.). When it was my turn, he picked a very hard song that he knew I would fail at, and I would have a few times if it wasn't for no-fail mode (I got an 82%). This 'act of revenge' upset me and I didn't want to talk to him afterwards.
TL:DR Should I be angry at my bf? How do you deal with competitiveness from your SO?
