I think it helps a WAW in an A to see the OM's attraction start of fade. If she can leave the A seeing him less than what she thought he was in the beginning, then I believe she has a better chance of staying out of contact with him.
If a woman leaves the A still believing OM was her only chance at true happiness....then it's going to be very hard for her to stick to her resolve not to check up and see how he's doing.
So, I hope this will help you to relax a little bit more. I pray for your M b/c I believe you are a great guy with a sweet little family.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
