So long story short. I have been with boyfriend for 9 months now. he is amazing and caring in all ways. I was on his computer whilst he went to gym yesterday. he knew I was borrowing it as I was typing up my CV. I clicked on a chat forum by error as I didn't know what it was. turns out it's a gaming chat thing. he is big in to gaming. now I could see there was one chat from a girl I know he watches a lot of (gaming) and I guess I was curious. I know, I know. it turns out she's actually the girl he went on a date with 1 month before meeting me. He wasn't interested in her as he had told me when we first got together. she had really bad teeth and it's true- she does. Anyway I can see there messaging and it does go quiet when he gets in to the relationship with me however she seems pissed off with it. so back in November she messaged him again and they chat...then there is voice call and several last week. Then he jokes about and messages her 'vagina'. i really want to talk to him about this as I don't think it's fair to me. he wouldnt like it. I just not sure if I am overreacting or how to approach the conversation?? help please!
