Your fiancee is a hypocrite. If he got upset about you doing something he told you you should do, he's a hypocrite. He's probably upset because you didn't get the other woman to go to bed with you while he was there. He probably had all kinds of fantasies about two women together, but when it slapped him in the face and he wasn't part of it, he freaked out. You might want to think about whether you actually want to marry a guy like that. Or you may decide that you'd be happier being a lesbian. That's something you have to explore for yourself.
