you should do nothing. if you start trying to do something she'll see you as a jealous person who is needy and actually go see the other guy. if she DOES see the other guy then she's obviously not that into you. i don't know about most guys but if my girlfriend goes out with other men, i'd probably start lookin somewhere else. that's always trouble when your girlfriend goes out with other men. especially to see a movie. the guy wants to fuk her.
think about it this way: if a girl asked you to see a movie and you already had a gf, would you go? if you did, that probably means you don't care about your gf that much.
Why on Earth couldnt you go watch a movie with a female friend?
I'm a make-up artist and a dating coach. In both professions I meet tons of girls, whether it's a model on a shoot or a girl met in a bar during a bootcamp, I do stay in touch with them. Some become friends of mine. We hang out together, party, go to the movies, play the wii or just shoot the crap on a sunny terrace.
Most of them have met my girlfriend, they became friends too.
In short, when my LTR was at her parents in Germany, a female friend calls me up to go and watch Sex and The city 2 (imagine a theater full of chicks. I felt like a chocolate bar at Fat Camp) I gladly went with her and topped it with a couple of drinks and we went to a club.
So? Does that mean I don't care much about my girlfriend?
