"well you're the one who wanted to have sex with a girl!"......nah, i couldn't have said that, would have been cruel and i don't want to be a cruel person. i don't think you do either. it must have been a terribly difficult few minutes....minutes that seemed like hours perhaps.
i'd take the call, let her apologize, accept the apology if you believe it is heartfelt and sincere, and calmly and kindly tell her that you want no further contact, ever. then execute on that.
and some people wonder why we aren't more open and more accepting of ourselves.......this too shall pass, don't stop being you and please don't be ashamed ~ have compassion for the less fortunate (you know who she is).
