Sounds a lot like my H who I have discovered had Asperger's....I couldn't engage him in any meaningful conversation as he could never figure out where in the world he was himself coming from.....

But then who in the world gets talked out of signing the loan papers & the deed on a house that is being purchased in a marriage when one knows that EVERYTHING is joint property.....sounds like there is some serious lack of knowledge on how to deal with real life situations on OP's part.
