My 21 year old boyfriend has been diagnosed on the autism spectrum and I am trying to understand if this is part of his autism or if he’s just being mean. We were playing a racing game on the PS2 and I kept winning every game. He kept losing and crashing and was getting angrier and angrier. He had a rage/meltdown and threw his remote control and started cussing at me and yelling. I told him it’s just a game and he needs to calm down. He had a meltdown over this, saying it’s “not fair” and that when he crashes I need to show good sportsmanship by stopping my car until he’s able to catch up with me. I left the room for about 5 minutes and he was fine when I got back in the room and he apologized. He got like this earlier today too when he lost the remote control to his TV and was feeling frustrated/overwhelmed. He also told me that he used to be like this as a child and would beat his remote controls into the ground in a blind rage if he lost. Is this apart of autism or does it sound like something else?
