This is how Nearly Exh behaves, stillstrong. He is NPD, FWIW, and what I've finally learned-I think-is that it's part of his ego boost if I need something and he can choose when to respond-or not. I suspect it's kind of like a game, even if he has an answer.
I, on the other hand, don't want anyone waiting for me for anything, nor do I want to owe anything, so it makes us very different and part of what some of the problems he made worse were.
There's generally no apology from Nearly Exh, either. You get what you get and you don't pitch a fit. Luckily, I have a lawyer now and I turn to him even if it costs money, but I do wait a period of time in between. I have to get really angry at Nearly Exh to get him to consider budging. Usually it's a threat from an outside creditor that does it, like when things are going to be shut off-it's extreme, so I know what you are dealing with, I think.
It's very frustrating, to say the least, and I'm sorry that you have to go through it to get things that are due you, especially, just, so. Yes, it is that way here-Nearly Exh also has passive aggression, if that's helpful and it gave me some things to read. He would pile up his resentments about me and then when I needed something, he wouldn't do it. I never had a clue of the amount of "upset" he had been at times, because he can't stand conflict and if he showed me he was upset, it might make a problem-there already was a problem!
I wonder if your WH has any of this going on that he's hidden, or some other things?
Sorry for my long post and I hope things get better. Maybe soon, you won't need very much from him anymore.
