I'm glad to hear about the GALing. That's honestly the best part of all this mess. We're just all a bunch of fit, hobbie happy, jolly idiots...lol.
You may want to contact an attorney state side to see if they can give you some clues as to how the divorce would translate. Marriage and dissolution of marriage laws get sticky from one country to another.
Honestly you sound like you've BEEN doing pretty great on detachment for what that's worth.
Lastly, I had some one bring that stong woman thing up to me. But I just listened to and Esther Perel pod case with a couple on the brink and the woman was very A type pre-kids. But when the kids came H had this very like weird man of the house awakening and he kept taking over more and more and kept not letting her do more or anything to help. Then resented her for being weak and making him do everything. I honestly don't know that it matters what the LBS is like. I think if you're an A type LBS they KNOW you're going to pick up the slack, but if you're a B type LBS they expect you to pick up the slack because you have to. Like all of this I think it's really more about the WAS/WS.
