is not an oxymoron. To judge a parent who moves away to accompany a spouse, in my opinion, is wrong. A child does have a vested interest in the second marriages of both natural parents to stay intact and happy...if Mom had decided to divorce her spouse just to stay in closer proximity to her child, do you think that choice would also be damaging to the child? What message does that send to the child?
Move-aways are a reality and divorced parents should plan and work together for the mutual benefit of the child...not condemn each other and spend more time finding blame or culpability without looking at the entire big picture.
