My gf and I have been together for 7 months now. We have been very open about our expectations from each other from the beginning. I never had any problems with her having male friends, she can talk with them or do whatever she wants but the one thing I am not comfortable with is her going out with them one-on-one or hanging out, let alone going to the movies. This is not something which happened recently but a while back that she went to the movies with one of her male friends. I have asked her before that you can hang out if it's a group of her friends. Or there are her female friends with her. I now want to clearly tell her that I don't want her going out alone with her male friends. How should I go about it? Should I tell her directly? We recently talked about something I was uncomfortable with and it went well so should I do the same?
TL;DR – Didn't like gf going to the movies one on one with her male friend. Want to tell her.
