Tomorrow is 24 months from

Tomorrow is 24 months from the DDay that revealed the undeniable evidence of his sexual betrayal. He let me go sixteen more months (with a trickle of this and that and lots of deception) before I FORCED him to come clean that the one I knew about wasn't the first. And between the first (which was a long drawn out emotional/sexual/entangled affair) and the second (which was a nasty sex in the bathroom for 16 months affair), there were several other women that he had some level of inappropriate contact with. So I had him take a lie detector test and he passed with flying colors. And then yesterday I forced another confession. And this one he was asked on the polygraph and he PASSED. So now I am a wreck. Could it be that the way his mind thought of the answer and the question were not congruent? Could it be that the mind of a newly (re)discovered cheater can't think clearly? Or could it be that there are many questions on that text that he lied about but somehow passed anyway??? Help! Has anyone else had this happen?
