If you would prefer not to move yet, DON'T. Do what you need to do for yourself right now, don't base anything on her unless/until the two of you are a true team/couple again....just my thoughts...
Or put another way
If there was NO W in the picture, would you want to move right now? B/C there is always the possibility you get there, and she leaves, then what?
(This is based on a friend who wanted to move to a new town b/c her sister lived there....she was asked, "What if your sister moves in 5 years, would you still want to live there?" You have to do what YOU want to do....)
