Personally, my XW has never once shown a glimmer of regret and can kind of make you second guess yourself after awhile.
Yes, it can. However, I would argue that they *all* think it. They all have it. It's just that some of them say it, and some of them don't. Your XW still has dork boy by her side. If my H was totally happy with OW, I'd have never heard the words out of his mouth either.
