They feel it. God is in their heart every day telling them it is wrong. It is overshadowed by the euphoria of the A and the noise from thier cheerleaders. They set themselves up to crash hard by making the A everything. In my sitch she is giving away all D issues just to be with the OM ASAP. He is twice divorced (2nd one in Dec) and the odds of this working out are very very low. When the A crashes then the guilt rises back up as anger and bitterness. He will probably direct it at you (because that is what he knows). I have heard the the A crashing hurts worse that the M ending to the WAS. Who knows. I am suprised at how quick your D will be final. Do not take any blame for his A. It is your decision on the D but he can stop it or delay it too.
