<human>: My girlfriend (16/F) went to a party at a friend's house the other night, and got pretty wasted. There were a few girls, and a few more guys (I know that at least one of them has a crush on her). She didn't tell me she was going to the party or that she was drinking (it was her first time drinking heavily). She told me that she shared a bed with one of the other guys there, but I'm not really worried about him. I trust her completely, but the guy that likes her was supplying her with a lot of drinks, which I'm not happy with. We've been dating a bit over 2 years, and this is the first real disagreement we've had. I just don't know what to think. I'm generally pretty protective of her, but I don't want her to stop socialising. Any advice?
