(((((damajdancer))))) I am so sorry! I don't know why people are so stuid! There is nothing you did wrong! I have kids your age and I'm uncomfortable with those questions.

May I ask if you spoke to your brother about the situation later and what was his opinion? Did he think differently about the girl he was seeing?

I don't know what part his girlfriend played in the situation, she may just be weak. Too weak to stand up to her friends. In any event it doesn't say much about her character, and I hope that you're brother sees that her treatment or lack of compassion for you is a major character flaw.
