Been thinking about some of your recent posts and am not sure his filing is a "done deal" - unless you want it to be.
He: *Held off nearly a month before telling you he'd filed *Is moving closer to you to "be near son" *Has been texting regularly *Stared at your hand when you touched his arm recently, as if he was surprised that he was still attracted to you *Was surprised that you were thinking about moving
I may be wrong, but he sounds like he filed under duress from OW. Check with forum vets "Greek" and "The Wifey" - they both had WAS who left, filed, and then returned. I'd also solicit a man's take on the matter from Puppy and Allen.
