I'd be careful trying to figure out the source/extent of h's guilt and jumping to conclusions (OK, you were just mulling, right?). Sure, yes, I suppose he could have had a PA and that could be leading to his guilt...he could also have WANTED to had one (but didn't for lots of reasons) and that could be a powerful guilt inducer as well...OR maybe he's completely guilt ridden over the EA! also, just because "other" WASes appear to want to forget and move on, don't underestimate the depth of their guilt of EA's or the like...not everyone shows guilt in the same way, right? so a WAS that pushes it all inside may be feeling equally guilty as h who appears to be laying it all out there.
I spent a bunch of time contemplating whether or not h had a PA and mostly I guess I've moved past it. (don't forget, though, it's been 2.5 years!).
Would it change what you're doing right now?
Finally, and I mean this as gently as possible...you say that you want to "move on" but, TBH, if I were your h I think I would feel confused about that at times (and perhaps that's contributing to his guilt?)...there are times (least from your posts) where it seems like your interactions with h signal that, in fact, you're NOT ready to move on from the topic. That's perfectly understandable...but it may also be a factor in his guilt/reaction to you so I thought I would (gently, kindly, best interest at heart! ) mention it.
