if you do a search for throughtherabbithole or nickel you'll find a person's threads that helped me a huge deal. She was a walk away wife and post divorce realized she still loved him. He'd begun a relationship and she offered him just friendship. After ther threads end I was filled in by other board members that they got back together, remarried, and have a child together.
I learned so much about offering frienship on thier terms from her posts and what others posted to her.
