I don't understand this. He and I are friends with benefits; we have never been in a relationship. And he even said we were not exclusive, that we were just casual. Now he is bringing up how I am not faithful to him because I told him I went on dates with other men. I don't get it. Am I missing something here? I did meet his mother, but he still has been saying we are just casual. He even said we were not sexually exclusive, but now he's talking about how he even said it was ok if i dated other men, but now I am not faithful?
