Much of what you just described is similar to my sitch. W's "plan" is predicated on her moving out, I keep the house that way I can share D 50/50, she's free, I'm there and all lives happily ever after. Selling the house pops MANY huge fantasy bubbles in her plan. Thing is it would make 50/50 custody of my D much harder, but here again I don't need a SF home if it's just me 50% of the time. As I say multi-faceted topic and decision.
Oh and I forgot the kicker of her plan, she worked so hard on the MR during S, but he was the bad guy as he started dating imaginary women and so she had no choice but to D.
Yep, good stuff here. People endure much more hardship to make 50/50 work.
Also, on the kicker. That is her fantasy popping. And trying to find another excuse to continue on her "plan".
