It's just occurred to me that this whole thing is about his dick...
Or should I say his masculinity, trees you mentioned I think it was his idea of another baby, so that's unconscious bragging rights number one. Look my seed is still potent I can make fire for I am MAN.
Then takes another woman to his bed, look I'm still virile and attractive she wants me, more bragging rights quietly to friends, plus pregnant wifey, wow he's practically THOR
I think your WH is feeling threatened, something in him is struggling, I don't want to come over all armchair diagnosis, but I bet he's afraid of growing old or losing status, deeply jealous of you and maybe your success, chain you to kitchen sink with baby
You always come across as so capable in your writing, do you think there might be a little bit of him that thinks he's surplus to requirements? The only thing thats working for him is his dick!
Even his gaming shows a need for well being needed, look for I am in a clan I am respected and needed to fight the good fight. At home your in charge, in your job your cool,calm considered, no one gets anything past you.
I don't know if he regrets any of what he has done, I think he now knows he's got your attention, I don't think he knows what he wants from it though .
Unless he has thought about any of this on a much deeper level, and isn't still coasting along on a sea of testosterone which I'm sure he is, he can't be trusted to have your back.
He's a jealous little boy who threw his teddys out of the pram, he just didn't think he would have to go and get them back himself.
