My girlfriend and I have been together for 5 months and enjoy going to parties together. We both always have a great time and are comfortable doing things together and splitting off to do our own thing and then reconnecting. We have a lot of the same interests which helps. We both drink but (without being insulting) my girlfriend drinks more than I do or at least often ends up more drunk. So the main thing I find challenging is how to look after her without spoiling her fun? Obviously I get worried seeing her drunk and doing things that are probably safe when sober but no so much when not. But at the same time I don't want to act like her dad, so that fine line is hard for me, especially when surrounded by groups of people who are doing the same things she is. A few specifics now:

• What are some good ways to look after her when I can see she is not sober?
• What are some good ways to encourage her maybe it's time to go home or to slow down for a bit?
• If a friend(s) of hers say they'll 'look after her' what should that mean for me, since I still feel responsible?
• If things get to a point where I am really concerned but not able to encourage her to leave/slow down what should I do?

We have already talked about the above together and she trusts me enough to do what I think is right to keep her safe (she's fully aware of how 'fun' she can get), it's just that how a person reacts to the above when sober vs not, is different, especially when you are having fun.
