I am in a similar situation, but I would look at her reaching out to you as a positive. She is at least keeping a connection alive with you, and you have to take advantage of that whenever possible. In my anger I too probably would have told her to sod off unless she wants to talk about the marriage, but again, she opened the door for you to help her. I would think about being her friend, and try to be an indespensible friend. It might stir some old feelings. Flings with other people rarely last. She may need a dependable shoulder to cry on one day. I would keep things as positive as you can considering the circumstances. Just my $0.02.
