Damn, I'm sorry. Sometimes people will lie to themselves about love to try and force themselves to move on for whatever reason, which she could be doing here. I think it is very important that you dont lie to yourself and pretend you arent in love when you still are. Try to get out there and meet new people, but I would not suggest faking interest in a relationship with another girl if you're still in love with the girl from your cabin. The best that can be suggested I think is to try to talk to her, and if she won't have it then there's nothing you can do further about the situation. Good luck my friend.
