Have you in my prayers Phoenix, as with your mobility and other problems you have enough to contend with. Coping with a tantrum throwing, offensive and non-caring man as you are, must be the pits, and thank God for your sons.
I have heard of "injured" hotel/motel guests suing the venue for various reasons, but never these places charging the guest for hurting himself. I wonder if he didn't throw a real tantrum, and cause damage to the room and also upset other guests and that was why he was on one side of the door and his gear inside.
Maybe it is time to look at options for removing him from causing anymore unneeded stress to you all, by either him leaving or you doing so.
