I get annoyed about this too, not because of girls but because I don't understand why boyfriends and girlfriends are supposed to have seperate friends and go out at seperate times/places. I really don't enjoy being in entirely female company so I find it hard to understand the concept of a lads/girls night. The idea that people are not supposed to enjoy the company of the opposite sex as much as the same sex annoys me and puts me off. If I don't want to be with my boyfriend, it's because I want to be alone.

I don't have a problem if one person wants to go out and the other doesn't want to/can't. But why would you be in a relationship with someone if they weren't one of the first people you thought of when you want to have fun aside from sex? Why can't both groups of friends all go out together? If someone can explain why this 'rule' isn't indicative of a bad attitude towards the opposite sex in general, I might be less annoyed by it. It seems to be changing for me because I have been there a few times and he says he has more fun when I'm there, but I think it's going to take a while for him to completely shake off the whole idea that I exist to ruin his fun as I am an evil female.
