Thanks DnJ. To my knowledge W has no intention of getting a L, has no way to pay for it that I know of, and I believe her intent, as she has said a few times to me is to copy her friend's recent D and work through things together. Her friend and her ex just paid a lawyer $750 to make sure everything was square before filing. I would have no issue with that except I know we won't agree on anything and I would rather sell our house prior to D.
W wants to D, then live together until D18 leaves next Aug/Sep for college. None of that makes sense to me. Then I guess sell the house at that point? I haven't heard of anyone else doing that. If she wants a D, then just leave.
I do see what you're saying about being upfront about it. Custody of my daughter and whatever spousal support/child support I'd be paying is way more important to me than any lawyer fees and it's weird that W apparently doesn't think so. Or maybe she's just hoping I'll agree to a terrible plan, the same way I was hoping she'd suggest one.
