Hi guys...

So, I'm a gay teenager and I'm out to my dad, my sister and a few of my friends. Anyway, the reason for this post is because of a friend. Two of my friends are doing a theatre workshop all week and I was talking to one of them. The boy I was talking to had said that he asked the girl if she knew me and she said, "The gay one? He's my GBF" and she knows how sensitive I am. He didn't know and she basically outed me and I wasn't ready to tell him yet. She could have put me in danger and I thought she was a true friend. What do I do about the situation? What if she does it again?
