Hi, I'm trying to get a new perspective on a problem that my gf and I had. Here's the story:

I am 23 she is 20. We live about two hours apart. We have been dating for 6 months now and things are getting serious. We have been talking about her moving in with me.

Two weeks ago she went to tailgate with a couple of her girlfriends. She ended up getting drunk and sleeping in the same bed as another older guy (29). She says that she meant to tell me the day after but that she forgot... I just found out about it this past weekend. She swears nothing happened and that it was just a place for the two of them to sleep.

I consider this cheating. Sleeping in the same bed with someone of the opposite sex while you are in a relationship is not right. I thought that was a given, but she seems to think it wasn't a big deal. I am more conservative than she is I guess. I just can't imagine two drunk people sleeping in the same bed and not fooling around. I feel like that is a recipe for disaster and she shouldn't be putting herself in that situation.

While I was single, if I was drunk and a girl was in the same bed with me there is no way that I would be able to stop myself from making a move. How am I supposed to believe that this guy didn't want her? Furthermore, now that I am in a relationship I would never sleep in the same bed as another girl…that is just plain weird. Am I overreacting? Is this not a big deal? Is in normal for this to happen? I really need another perspective on this situation (guys and girls). I have no one that I feel comfortable talking to about this and I am driving myself crazy thinking about it. Thanks.
