I didn't want to come right out and say it but it isn't uncommon for the cheating spouse to be advised to seduce/sleep with the LBS so the affair is wiped clean.
As per my attny he also told me it isn't uncommon for the cheater to attend IC for a short while to show the courts "he/she tried". By then the LBS is so ticked off and has gone dark and the WAS can actually use it against the LBS. In my state there is a vested interest in keep marriages in tact hence the horrid divorce laws.
