I've thought a lot about it recently, ForGump. I'd LIKE to tell her she needs to move out if this life is really oh so hard for her, and I'll stay in the house and have the kids 100% of the time. We can work something out where she can visit at set times. In truth, though, she's a very good mom, and this wouldn't be in the kids' best interests.
Where I think we'd end up, because our youngest needs to stay in this school district at least through this school year and next is some sort of short-term apartment or studio lease where I go part of the time, and she goes part of the time, with the kids always at home, just with a different solo parent per whatever schedule we agree to. It would suck in its own ways -- mainly loss of time with kids, but also because I'm just not an apartment person (light sleeper, like to escape to recharge) -- but then the status quo is pretty exhausting.
