OP kinda sounds like…. ‘If she moves away, and she is successful she may never come back, and if she isn’t successful, when she comes back she will have so much personal growth through the experience that she won’t be interested in me anymore. So how do I derail her plans and keep her world small?’

Or as the old song asks: “How you gonna keep ‘em down on the farm after they’ve seen Jerseeeey?”
