This may sound callous, but I think it's time to flip him the bird and pack your bags. If I were you, I would line up a divorce attorney, tell that man "Your kids own you, but they will not own me" and go.
Don't stick around long enough to get stuck with his kids' therapy bills.
I think you may have a point, Myrabeth.
One small thing, though - I think DLEE mentioned earlier that her husband moved in with her, so I think it's
his bags she should be packing! He will just have to find an alternative venue for entertaining his precious darlings.
