I know where you stand on the divorce issue...and while I may not agree with it, I do respect your stance on it. I was trying to come up with things for you to do, but I think Honeypot basically stated what I was going to say as well.
There are other people who are involved in animal rescue/shelters, call on them. I know this is likely to result in a meltdown from your W, but it's setting and reinforcing a boundary....having a boundary without reinforcing it is pointless. She's proven time and time again that she really doesn't respect your boundaries, and that's not terribly surprising from someone with NPD. For a person with NPD the world revolves around them, no one else...that's a frustrating thing to live with I'm sure....and I can only imagine what it's like to try to wrap your mind around the fact that what she has is most likely never going to change, especially with the convictions you have.
I also do happen to agree with those who've stated that by telling her you will never leave...you've removed much of your power. Someone with NPD is likely to take advantage of that. So, if you refuse to think of leaving as an option then you are going to have to do some drastic things within the household to set boundaries....such as shipping off the dogs to other shelters. I know of one here in Oklahoma, a friend of mine here at work runs it....I'll be happy to ask him if he knows of some shelters that can take the dogs you have in.
