<human>: I'm 23, she's 22. Started going out midway through 2009, so nearly two years together.

I was invited to this lan about a month ago, and have been looking forward to it. I also invited my girlfriend, but she declined because she thinks she'd be bored and just have to sit around doing nothing because she doesn't play video games - she is most likely correct, but I think she could have put in an hour just to improve her own comfort level with it.

She is never happy if I organise/do anything with any female friends, regardless of if I invite her or not.

Now, I kind of have the mentality that I can't back down on this kind of thing, because doing so would justify that she can control my platonic friendships with women - something I'm not up for. I've told her I believe the issue isn't that I'm doing something unreasonable, but that she has her own insecurity/jealousy issues that she needs to work on. She countered by saying that she can't think of any guy who would stay over a girls house when their gf doesn't want to.

When taken out of context, I'd agree with her - but I really don't think crashing at a lan, along with 5-6 other guys, + one of their girlfriends + the host is the same situation, I liken it to crashing at a party, which just happens to be at a girls house.

I told her if she feels that uncomfortable about it, she can feel free to pick me up at 2-3am when it finishes up, but she has told me she's not inclined to do that either.

Summarize the given text in a few sentences.
<bot>: going to a lan organised by a girl, gf is jealous and wants me to get a cab home with my gear at 2-3am.
