I'm so sorry to hear that NY - it is devastating to find your partner is still in touch with AP. I went through the same and I truly empathise - ugh.....
For me - that was boundary time - I won't live in a situation where you are in contact with AP. I just knew I couldn't live like that. What does it mean for you?
The thing is - once that affair line is crossed, even though someone might want to turn back and try not to lose the main R - the A is addictive and it is hard to sustain. It does truly have to run it's course and it sounds as though it hasn't yet in your case.
Have you confronted your W with what you know? Keep posting my friend - we are all here for you. Xx
