Am I a b*tch for doing this?

My boyfriend is in the services but as of right now he is in Florida. We just got done talking on the skype when he told me that he was going to help his female friend move into her new apartment,which I'm okay with. The part that upset me was when he said that it was going to be only the two of them and that he would spend three nights with her. He showed me a Facebook comment by her and it said "hey ur still going to help me move in right?Its only going to be the two of us plus a bottle ". The bf says that he promised to help her out awhile back and the other two friends can't help out anymore. Was it wrong for me to be suspicious? Then he brought up the fact that I hung out with a guy and never told him about it till couple days later. But this was before we started saying "I love you" n stuff and since I haven't hung out with a guy in more than five months.... alone that is.
