Hi mountain_west,
Your situation sounds very similar to mine, only we have just been separated for 2 weeks. I can't imagine how painful it must be to be in limbo-land for a year!
Like you, my WAS and I don't have kids together, and that makes it harder for them to see the changes in us. I wish there was more advice for people like us who really don't have many opportunities to communicate with our WAS.
IMO, I think you should move so you can completely detach and not have that long commute. You have given her a year, and it sounds like it's going to take something drastic for her to make up her mind. I just feel so sorry for you. I think you know in your mind that you need to move. If she truly wants to be with you, she won't blame you for deserting her. Wish you the best!
