To answer your question, yes I would be willing to go to counseling if she were to present the idea. Like dday said, I would imagine it would take a long time to regain trust. I have never really been the jealous type, but essentially became a CIA spy after my ex informed me she wanted a divorce. This included setting up spyware on our computer, looking through her files, cell phone records, and even her work email. I still cannot believe all that I found, and I would guess it would take some time to once again not have the urge to look through her personal things. When taking that into consideration, I sometimes think 'why bother', but at the end of the day I always think the positives outweighed the negatives.
I too often think she will want reconciliation, but realize I need to continue to GAL and have a PMA. The tears flow less frequently, but still appear from time to time out of nowhere.
I agree with dday in that being left for someone else is somewhat demoralizing, but I try to look at it as her problem and not mine.
