Other than the excemtion on the house, (which will leave her broke), I'm pretty OK with everything else.
But the custody thing bothers me. It was agreed 50/50 but the A and OM (D's exposure to an almost guaranteed failure) has me concerned as she shouldn't be exposed to him on equal time with me. It will confuse her.
I think you can position this separation time as a "dress rehearsal," either for divorce or for reconciliation. And make it clear to her that while you normally would have no qualms about 50/50 custody, that you have no intention of going for anything less than full custody (with reasonable visitation offered to her) of Calla, considering your wife's current reckless behavior. And that -- based on how she behaves during the separation period -- you may or may not change your mind.
I did this, and never wavered. Made it ABSOLUTELY CLEAR to my wife that I had ZERO INTENTION of letting her have custody of our two boys while she was meeting OM in parking lots for sex in his truck, etc.!
