Man, those must be very special dogs! But, I see your POV. If she's disrespecting you (and she is), then she doesn't come to your house or visit anything therein.
Continuing NC and not allowing her in your home, or visit the pets, are about all you have at this point. Has she asked for any of her things that was left behind? Has seeing the dogs been the top of her list?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
