One of my biggest worries was my W's desire to relocate to Nashville, TN (the same place where the OM lives currently). She has indicated this to me very early on, and even suggested at one point to fly down there with me so we could check out the city and neighborhood. At that time, she also indicated that she wants our son to finish 2nd grade here, so the plan to relocate would be a gradual one (about 1 year). She also said she planned to sell our house in the spring of 2015. She also told her parents about these plans, and she and the OM even offered to buy a house with a detached suite so they can live together, help out with the kids, etc.
My FIL and my W were driving together yesterday to meet a realtor (some paperwork for his rental apartment) and my FIL commented to her that if she doesn't move to Nashville, that he wants to keep his apartment. My W replied back, "Who said I'm moving to Nashville? If you want, you can move there. I'm not moving there."
