Why do guys start acting more distant towards other girls when they have a girl vs when they didn’t have a girl? Like… can’t they have close friends that happen to be girls while mostly spending time with their own girl as well?
It could be because their girl doesn't know you. Some girls get uneasy when guys have girl friends they don't know. I've been in this situation as a friend and it's all about being respectful and understanding to your friend and their relationship. I've learned to keep my distance and still be there as a friend. I've also built friendships with some of the girlfriends as well.
