You know, Mighty, I hate to say it, but I think this was a false reconciliation. He felt oppressed by his impending fatherhood and the fact that the grass wasn't greener (and maybe was fighting with HWW) so he came to you and said all those nice things.
Now the baby is here, he's bonding with her, and you can bet HWW is doing her darnedest to reel him back in - and apparently it's working. He's starting to retract some of his statements etc.
It doesn't mean I'm right for sure, but I'd be prepared for him to go back to HWW at least once.
(btw, if he does - GET OUT THERE and LIVE. Let him worry about you going dancing with other men etc. Doesn't mean you have to or should date, but it's often amazing how their minds clear once they see their spouse has moved on.)
