I can tell you that it takes time for them (MLC'er) to see the errors...they don't want to because it does hurt to face your mistakes...
My H didn't admit OW was mistake for well over a year...I kept quiet about it...during the time he left and through this phase he was convinced that she had "saved his life"...those were his feelings until he had been home for a while...now he feels very differently...so while he may be over OW...he still has to reconcile things in his brain...it takes time...and it takes love, kindness, and patience on your part...
So I would like to add a D to what BND wrote
D. Continue to GAL, show unconditional love, avoid confrontation, show him the new and improved you...be patient, kind, and give him time... So hang in there...the light is showing at the end of the tunnel...Lin
