I don't know your WH and of course I don't know you so my comments are only my best guesses. But I will tell you a little story about my past situation that relates directly to this:
I have seen alot of actions from my husband that makes me believe he is sincere about what he did or didn't do. He realized it's still cheating even if no sex was involved.
My WH was one of the rare cheaters around here who, when caught, pretty much confessed to everything. There was VERY little that he told me later that I didn't already know (meaning he may have provided me more detail later but he told me the basis facts from the get go when caught - what a blessing that was I didn't realize for a long long time). BUT for some reason he kept something from me. My WH had a workplace A for about 20 months in a very secure facility (with a very high governmental security clearance) where had they been caught having sex on site they would have unequivocally lost their jobs - so they didn't have sex there but one time (I know this not because he told me but because I later - like 16 months after d-day 1, had his phone forensically recovered and found text messages from her talking about how she wished they could do it at work, how many days, weeks, months it had been since they last had sex, etc, confirming they didn't have actual sex for a very long time). He confessed to all the disgusting sexting (which IMO was far worse that sex), and the video masturbation, and the when/where that they actually had sex (which was almost entirely in the beginning of the A when I was out of state for work), but for some reason he never confessed to the time I knew about from an email I had seen, and never told him about about 4 months after d-day 1, which was the single time during an entire year that they met up and had sex after I got back from my out of state job..
He denied over and over and over that sex happened during that year - all the while I KNEW that it did and said nothing. I mean honestly he was so convincing that I almost believed him even though I had seen the email with my own eyes. Only when I had the phone sent out for recoverery - which was well over a year of him lying about this one stupid thing (by stupid I mean in the sea of things he had done withholding that one event from me seemed outrageous) did he sheepishly come to me and tell me he has something else he needed to tell me. I don't think he EVER would have told me about it had he not been concerned that I was going to get the phone back and see messages during that time and know he was lying.
I have NO idea why a WS would withhold something when they have been caught. I have no idea how my WH could seem so sincere and yet be so totally dishonest. But it can happen and unfortunately often does. I would highly doubt that your WH is being 100% honest with you. What he is and isn't lying about no one here knows, including you most likely. But memory loss and making up stories for what exactly?
Lies are tools of manipulation. They are designed to manipulate. Everyone has lied - me included. And there was a reason, and normally it is to control the outcome. So try to allow yourself to think of the motive for the story you are being told - by him and by her. The chances are that it is not 100% the truth (it may be but the chances aren't good). Is the AP worried you might tell he spouse? I mean shutting you up seems like a pretty decent motive - so she takes the blame so she seems like the bad one and you aren't so mad at your WH lessening your motivation to blow everything up?
but my concern is for you - you seem to want to believe him, and I get that too. But honestly put yourself first now. You are completely entitled to (and in my opinion) should not trust him right now as he has proven himself to be, at bare minimum, untrustworthy, no matter how much you want to. Trust will come in time if its real.
