Moving is traumatic. More than I ever thought until I did it. I do think it was our big move from slow, Southern city with big flooding problem to big, sunny Florida city of northern transplants that tipped the scales in favor of his old girlfriend and brought her to the forefront of his mind.
But dreaming a dream together is a good thing. So, if you and she both buy into the dream of moving to MIL's town and if selling the current abode isn't too difficult, then this may be something that draws you together. But as emotionally fragile as W is, you will have to be very attentive to encroaching depression after the excitement of the move wears off.
