If an ex mistress approached the married man she had affairs with when they haven't talked in mths y would he just smile n say he feels bad about what he did and seem 2 her he didnt want to be there?

well it could be 1 of 2 things:

1) he wants to be faithful now and doesnt want you around to temp him or tell his wife

2)he doesnt want you as a mistress anymore....he moved on
