Angelgirl, I think Wondering said it very well.... you still have to tread carefully while he is still processing. He can only handle so much "truth"... for real. Can you even imagine?
I know that my husband fudges on a lot of things because he is creatively redefining what cheating is... if, in his mind, it is over with OW, though they are still in contact, he tries to convince himself I'm unreasonable for suggesting they are still involved.... I honestly have said "well, did you spend the weekend with her?" only to have him say "Yes, but we didn't have sex" which is another lie to HIMSELF, first and foremost... he cannot HANDLE the truth of what he's doing, which by the way, he refers to as "what I've DONE".... ummm, no.... DOING.
Did this particular snooping come about as you CAME ACROSS some of his stuff? That happened to me yesterday, but it was just some notes of his on the number for the power company in CT to get his electric turned on in their apartment THIS TIME LAST YEAR, so that was a slight trigger.... just a reminder of the REALITY we were living in...
So, back to snooping....I would avoid the emails between them at all costs... I would find those disks and destroy them, unless there is still a possiblity of a divorce action, in which case I would put the disk away just in case... don't read them.... he doesn't feel that way about her now, so they are only relevant to his PAST infatuated fantasy feelings and you know what those were... Going back over his FEELINGS is irrelevant..... the timeline, I totally understand.... you want to know if you were being duped and stupid while he was cavorting in the hot tub.... in theory, he should come clean.... but maybe let it lie for now.... he kinda confirmed what you figured out, so maybe that's enough... kinda like meeting you half way, LOL!!
I suspect that the more he progresses towards you, the less info you will need.... it's probably a little of each.
Do you think he has gone through OW withdrawal? If so, please describe if you can... he sounds like he's still not through his MLC, therefore unable to be fully committed to you.... you're still not getting the loving husband you desire, but he's trying!
I think that now you are dealing with the old "I know that you know that I know.... so just as long as we are clear about it, no matter what you don't tell me.... I KNOW!" and maybe that's enough!!
No more snooping for awhile....it could cause you to go off the deep end and set you back.... could be the handiwork of "the devil" here, as well, LOL!! To get you all riled up and insecure... go write down ten positive things about your R with your husband right now.... seriously!
