We suspect our best friend is gay, help?

Interesting how you ert that she "makes" you to this and "makes" you do that. If that is the case, then you and your other friends are pretty weak people. Personally, if I were this girl, I would RUN from girls like you. You sound haughty and you are NOT what I would look for in a friend. I wouldn't care if you were as hot as Angelina Jolie, your personality and attitude are total turn-offs, not to mention your paranoia on the subject. Go see a psychologist and resolve your issues with YOUR OWN uality!!
