I watched one of my closest guy friends cheat on his girlfriend tonight, a girl I was extremely close with for about the same amount of time as I've been friends with her. I've been friends with the two of them since before they were together, and they got together about a year and a half ago. Well, they became completely addicted to each other, and spent EVERY moment of every day together: had all the same classes, slept together every night, ate all their meals together, etc. well she finally couldn't take it anymore, and decided she wanted a life of her own so she transferred to a big university and joined a sorority. I guess he's feeling left behind because she has this whole new life that he's not a part of, and he feels like she's changing so much. she also told him that she didn't want to have sex any more before they're married (there are no plans to get married). *edit* she's VERY religious and has always regretted that she's not going to be a virgin when she gets married. She hasn't been out to visit him once yet (she lives 3 hours away and has a lot of stuff going on with the sorority), and she expects him to come home every other weekend to see her. When he goes home, she wants him to take her out, buy her stuff, etc, and gets upset when he doesn't meet all her expectations. Well I guess he's been feeling pretty low because I saw him last night: he was very drunk and complaining to me about how he just needed to have sex and how much he misses her. I took him home and put him to bed so he wouldn't do anything stupid because the writing was on the wall. Tonight I walked into a party, and there he was in the front entrance talking with a girl. He didn't see me, but while I stood there and watched, he leaned in and stuck his tongue down this girls throat. Twice. I grabbed him by the arm and took him out of there, telling him we needed to talk. Next hour was spent with him crying in my arms on the grass in the backyard about what a terrible person he is. I told him I was disappointed in him, but that a LDR isn't easy and he's only human. I also told him I wasnt going to tell her, although I would want someone to tell me if my boyfriend cheated on me. I told him not to tell her, either, because its not going to make anything better. Its just a kiss, its the first time its happened, and cheating is just the physical manifestation of a greater problem that needs to be worked out. Now its tearing me up inside. What would you have done in this situation? Sorry for the rambling, I've had a few.
