My best friend is an online one. We met over xbox live around 4 years ago and have been friends ever since. Finally he decides it's time to hang out in real life and makes a trip to Florida to see both me and my SO. She, being a gamer girl and always playing games with us, is also a very close friend of his. About a week before he gets down here they tell me they would like to do things with each other. (we have been broken up for around 3-4 months by this point) At first I try to keep it cool and tell them I am ok with it, because we are broken up, and she should be able to do whatever she wants right? (oh, man was that a mistake). A few days later I freak out about it and tell them not to go through with it because I obviously still have feelings for the girl and if my best friend fucks a girl I still love it would pretty much ruin both of the relationships.(but by then it was too late and they have already made up their minds) Well, eventually he got down here, they fucked, and went on their marry way. To them it was just a "Spur of the moment thing" and they were just living in the moment, but why would they do this to me knowing how I would feel afterward? Do they not care about my feelings at all? It has been about a month after all this has happened. Me and my friend don't talk anymore. The relationship with the girl was slowly growing better, till today, where we had a fight and now I feel as if she doesn't want to try to harvest even the friendship anymore. I still love her. Maybe I should just get over those feelings and move on... But I still want to try... I don't know why but I still do... After all she has put me through I still love her. Any advice on how you would handle this?
