(He hadn't mentioned it in 2 months, so I was really surprised and immediately sad.)
Unfortunately DB'ing doesn't always stop the D in its tracks. The same thing happened to me, my W didn't mention the D for 6+ months, then out of the blue one day she informed me she had hired a lawyer because she was too lazy (her words) to do the paperwork herself. She told me she would bring the papers to me the next week, and that was over 2 months ago and I still don't have them. So hang in there, even though he's talking about it again he may not act on those words.
