This may not be what others recommend, but I say keep moving forward and do what's best for you.
When I was done with BF I started making plans to move out of state because that's what I wanted for my life. BF said it was hard thinking that I would be across the country and he'd never see me again. I just turned to him and said, "That's what breaking up means. You don't get a say in what I do or where I go."
Many people think you shouldn't make too many big changes at once, but I'm all for a fresh start. Especially since jobs in your field are elsewhere.
I know you want to hold out hope W will change her mind and come running back home, but are you willing to put your future on hold to wait for that?
Have you seen a lawyer yet? I would do that ASAP. It's always good to know your rights and what you're entitled to. D is the ending of a business arrangement also so you should do what you can to protect yourself financially.
It sucks. But you can choose to find the silver lining (what you've learned about yourself and Rs) and work toward making a happy future for yourself. Hey, you should get something out of this crappy situation, right?
Hugs!
