Your H sounds like he's in a good place, really. If my WH said something like that-- let's be a family and take it one day at a time-- I think I totally would! Well, at least if he said it like your H did.
And it is great that you have met women going through such similar things. I especially like the pregnancy story. I can't believe she didn't tell her family. Seriously, that would be so hard. But it seemed to work out for her in the end!
