go with number 1 in mho. Why? B/c you can still get back together later and it's more likely than if you drag it out and change what is relatively warm and rather touching now, into a fight or another round of pursuit. Why on earth do that?
Nothing is irrevocable. I'd accept that a div is likely. So now, the goal is two fold: one, you'd like a remarriage/reconciliation post div. The chance of that is small ==but it happens, and my family is proof of that. 2 relatives remarried years after they divorced. It's much more likely to occur with option #1. (He won't be trapped into staying M to you, so #2 just eliminates the chance for a remarriage).
SECOND, you'd like as a second choice, a good R with him. Also much easier with option #1 and impossible with #2.
Seems clear to me. Congrats on having a good lunch. Except for him having a total 180, you got the best possible outcome in mho.
Again, congrats. j-
