Formerly wayward spouses on these very forums talk about how they SAW their spouse's changes, and their loving gestures, but they were blocked from feeling or appreciating them, because they were infatuated with OM/OW.
Absolutely correct. You emotionally switch off your H/W and yu focus only on the good of the OP. In fact the bad of your spouse is magnified due to your rationalising process and guilt ridding thoughts. Their good and love completely overlooked.
