I've been dating a girl for a few months now and things are great for the most part. However, we've had some issues recently with a couple of her male friends. First, she has a friend from college. She said they've never dated but they "used to hang out." She mentioned she was going to hang out with him (not the way they used to hang out) and I asked why she didn't invite me along. She said that he's really weird about meeting any boyfriend she might have, so he wouldn't want to hang out if I was there. I told her how absurd this was, she agreed, and she said she wasn't going to hang out with him anymore. Almost immediately afterwards, she had a group of her girlfriends visit her from college. They met this guy who seemed pretty interested in one of her friends. But her friend lives like 6 hours away from us. This situation has gradually turned into this guy hanging out with my girlfriend while her friend isn't around. Now, she was sensitive to how I felt about this, and she stated this new guy wants to meet me (he hasn't yet though). Because of this, it didn't really bother me at first. But over the last week or so, it has started to bother me. She likes the idea of being friends with this guy because they share a few interests that I don't. And most of her friends live far away, so she wants to hang out with people outside my group of friends. This is all totally understandable to me. My girlfriend is a really sincere, trustworthy girl, and she has a lot of integrity. She's given me no reason not to trust her. Do you think I have the right to be bothered? What would you do?
