My girlfriend and I have been together for over 5 years and have a son together. She is an open and outgoing person, but she doesn't make friends well with females. She has become friends with a guy that she likes to hang around and talk with from time to time. (This guy is married.) Well I am having problems dealing with this even though I trust her. There is no signs of cheating. I've been in another relationship in my past where there was cheating and I know the signs. But with my current girlfriend those signs are not there and I totally trust her. She also says she has no problem with me hanging out with female friends. I guess in the long run I don't trust her friend even though I trust her. Should I be concerned? Do I need to get over myself? Am I being ignorant? Or What? By the way we are all in our 30's.
