It has been a LONG time since I was df'd........but I still think of the handful of close friends that I had. I got in touch with two of them this past year, and yes, we resumed somewhat of a friendship. My situation was that I moved away. So I didn't actively witness them shunning me, I just sorta fell out of the picture. I think it would he hard for me to resume a friendship with someone who shunned me to my face.
I have to admit, the two that I got in contact with are both ex-dubs now.......and you can guess what we talked a lot about!
