new trying to figure it out

New on this forum. My husband has not been diagnosed but it seems to make sense to me. He thinks he is part of a research project and that everyone is just following a script. After a year and a half I asked him to move out, it was just becoming to difficult for the 2 teenagers living at home. He would accuse them of not being upset enough, not crying enough, and lying.
He moved in with his mom, who died this summer. He believes this was faked as well. He and his sister were named as executor but since he does not think it is really they are trying to have him removed. They are selling the house and he will have no where to live. Now he tells me he is no longer working since this is all fake. He can't make his truck payment or pay for anything else. His truck is in my name and he now owes the IRS for last years taxes.
When this was first noticed I took him to see someone who simply said don't yo think they would have had you sign papers for a research project. Got him in to someone else who said there was really nothing they could do.
What I am trying to figure out is do I sell the truck and work on selling the house, so I can file for divorce?
Not looking forward to the upcoming holiday. It is very difficult for the 3 children while they are older it is still very hard since they do not want to be around him.

Hi, newml5! You could ask more doctors what you can do for him and if you could have him comitted somewhere, for his own good. I hope his sister won't try to keep all the money she gets from selling their mother's house for herself. That money might help him have a place to stay.
You could ask a lawyer what's the best thing to do, so that you and the kids will be safe and so that he won't be alone and homeless.
