Is it fair for me to make my GF NOT get DRUNK anymore?

I think you've got a fair point, I'm a bit like your girlfriend. I find it extremely difficult to control myself when I'm drunk and I've cheated when I'm drunk and it ruined mine and my ex boyfriend's relationship. I understand your concern, but dont be too controlling because girls dont like it when guys are controlling. I think you guys should talk. Tell her your concerns and if she respect you and wants to make the relationship work maybe she will cut down on her drinking. I know it must be hard to trust her when she's drunk. I really dont want your gf to end up in the same boat as me, getting drunk and cheating and losing a great guy. If she cant trust her when she drinks (I dont think she can if she thinks that she may cheat) I think she needs to cut down, especially if she cares about you an wants your relationship to work. Maybe she could get her mates to watch her when she's drunk so she doesnt do anything stupid. You guys need to discuss it. It is a hard one because she's young and probably just wants to have fun, but then again too much alcohol clouds your judgement and makes you make a lot of mistakes. Use my story for an example; a girl who keep getting drunk and cheating on her boyfriend and then she's paying the price when they break up and cant get over it knowing it was her fault. There's nothing wrong with getting drunk, but if she wants to make things work with you I think she needs to keep a limit where she can still have fun, but be in control at the same time.
