O.O.
I've heard it said that forgiveness is a gift you give yourself.
Your own words describe how sick and upset you are over this.
Would it be so bad to be the O. that reaches out? To be the bigger person?
You don't give specifics about what happened, but I think if YOU respect the person you are and the choices YOU make, it shouldn't/wouldn't matter at all what others say.
Good luck!
