I used to think I would want to know all the facts if my W ever had a PA, but now after having dealt with this for the past 9 months I'm not so sure I would. I would want her to take responsibility and offer to answer any questions I would have, but I don't think I would ask many for my own protection. I would have to choose to set a time to just let it go and forgive her, and that would mean never bringing it up again. I hope I never have to cross that bridge, but if it's that or her never coming back I would cross it gladly.
Which brings me to a point. My W has already filed and shown no indication that she doesn't plan on following through with it someday other than the fact that she hasn't already. I live every day with this feeling of impending doom that my marriage will be over forever, but there is no apparent OM. If I knew she could have a PA, feel remorseful and then turn back to the family as opposed to running away from the family as fast as she can I have to say I would prefer to deal with an affair at this point rather than deal with starting a new life with someone else. Just my .02.
One day at a time.
