Well, I think he isn't necessarily snubbing you but fears that you might OUT him and just doesn't know what to say or do about his situation. He sounds like a very confused person at the moment. Maybe you should think about having a chat with the two of them and pointing out that while you don't care what THEY do, you do care about how they treat others in the process. Shunning others while they are doing the same, if not worse, is pure hypocrisy!!!
