I'm just going to ignore all her texts, e-mails, FB posts, and stand her up for our "friend dates" this month. I'm not going to go out of my way to initiate a conversation with her right now just to tell her I don't want to be her friend. She'll get the point pretty quickly.
In the meantime, I definitely just got asked out on a date, and I'm going. My wife left me for another man. If that's who she wants to be, he can have her. Maybe we CAN even be friends someday.
