Reading all of these responses, I'd say you've got some true friends on this site. It is sad that one thing can change a friendship sour like that. I have a best friend who thinks I'm just crossdressing...he doesn't know that I want to be a male. When I had brought it up a month ago, he said "You are not a guy! You are a girl! Please wear girl clothes!" I have been friends with him for 8 months and he's like my second half so it hurt that he said that to me.
His reason was selfish too. He just wanted me to stay a girl because I was "attractive as a girl". I tell him everything, even though we haven't been friends for long. I feel like I've known him all my life so it was a shock that he said that to me. But I learned from this thread. I learned that you shouldn't try your hardest to make others happy when you're sad/upset inside. You should focus on what makes you happy, not the people around you.
