Never been through a divorce, so I'm speaking somewhat ignorantly here, sorry. Been through some really bad breakups, though, where we'd lived together for years upon years.
How do almost all divorces end badly? If I got one, I'd just say, "Take it. Take it all. We'll reach an equitable solution for the kids (you get primary custody, but I get them every now and then), but you get the house, your car, all the crap, etc. I just need my car."
That's how all the breakups went. I was willing to give up everything just to get them the Eff out.
