Hey, so I (23M) am dating O(23F). She has other partners, I do not. We live relatively close, and the other day she told me she was going to go drive south to visit an "old friend". Ok, who is this old friend? I had to probe and ask, until she told me his name and their relationship, which is strictly a sexual partner.

Why would she hide that from me? She knows I've had huge problems with people cheating before, so why hide what your relationship with this guy is? Why could she not tell me right off the bat, and say "hey, I'm going down to visit this guy, who is this to me if you didn't know"?

So I called her on it, and her response was "I practice this life style because I do not like having to be guilty about decisions I make. You are kinda now implying that I should be telling you about decisions before I make them. This does not really work for me."

I dont know what to say
