Who knows, it's case by case? And I think sometimes they come back but they aren't ready to accept the reality of what they have done and how it's affected people. Most WAS's have an OM/OW, so it's not fear of being alone IMO.
It's just human nature to want what you can't have. We always tell people to read the pursuit/distancer link or the picnic link. People want to be wanted.
I don't remember a lot of what I've said, ever. I remember better how I felt. Adding emotions to things tends to affect memory. WAS's and LBS's are usually going through the most emotional time of their lives.
Your H is likely the one delaying it, not his lawyer. The lawyer works for your H. If the lawyer was backlogged he would likely give a timeline.
Your attitude is probably what has him second guessing. Just keep carrying on with your life and making it better. If H comes back, we'll see how you feel about it. If he doesn't, oh well nothing changes for you.

It is not things that bother us, but the stories we tell ourselves about things.
