God I hate FB! That's how the OW outed the A to me. My WH, although I already 'knew' in my heart, wouldn't make the break.It became a war of words between my daughters and OW. She is about as mature as a 14 year old. All the advice I can give is to keep in mind that the best revenge is living well. If it's just TOO uncomforable, then don't go; BUT, sometimes the things that we dread the most turn in our favor. You just have to decide how that relates to your particular sitch. She may be 'the new otherhalf', but she knows EVERYONE there knows exactly how that came about. Hugs to you.
