Maybe in a sort of way she is in the same boat as you, maybe the divorce made her open her eyes a bit, maybe she is the one who is being shunned now? I had kind of the same thing happen to me back when I was in High School, my parents friends, son worked at the local store, I went there to buy a birthday present for a friend, just some candles and incense. Lucky me I got him as the bagger, he commented on how I must be doing some devil worshipping as he was bagging my items, I looked at him like "What??" he looked down at the bag and walked away, the cashier looked at me like "Ok whats that about" I just smiled and walked out. A few years later, I saw that same guy at a Worldly party I was shocked to see him there and even more to see him smoking pot and making out with some chick, I take it he was DF'd mostly because I was more shocked that he talked to me like we were old friends.
