In an ideal world, maybe. Parents (single, married, remarried, divorced) make decisions everyday that are sometimes against the wishes of their child and sometimes those are made very much with the child's best interests at the forefront of the parent's mind.
I chose to move two small children 4000 miles away to a foreign country and a family court agreed staying with me, regardless of where I moved, was in their best interest. My eldest can't wait to move back to America but my youngest loves it here. There were much bigger (and more adult) considerations than friends, school, or even what remains of extended family. JMO
