It sounds as if you may have doubts about moving and so maybe you can listen to your heart and do know what is right for you?
Can you ask this Pdoc to help get you settled before he goes?
I worry about a relationship that involves moving to be near a T as the ultimate goal is for us to be independent and live our own lives, isn't it?
(Of course if my T moved right now I'd be in his suitcase)
