OP here again.

Yes, he talks to her alone sometimes. I asked him today. He says sometimes they even talk for up to an hour.

Yeah, she calls me normally. Almost every day, but thing is, she calls my best friend just as much. She also gets in depth with me, but of course, not him, but that's not the point. Does she like that guy that much that she has to call him every day?

I'm just going to talk to her. This is an ISSUE that needs to be ADDRESSED. I'm not going to act like it doesn't bother me, because it does. I'm going to ask her directly, why are you calling this guy so much? This is her first relationship so she may not see what's wrong with it, but there are certain things you just don't do in a relationship and this is one of them.

I don't care if I'm overracting. My girlfriend talking to my best friend for hours on the phone is not acceptable. If we don't come to terms, we won't be together, and that's that.
