Greeting knitted and welcome to Dhamma Wheel.
I have done the interstate move a number of times. Most recently, four years ago to Tasmania from the mainland in support of my wife's career and education opportunities for my kids.
I'm sure I don't have to tell you that if you are considering a major move like the one you are considering, then you weigh the benefits against the impacts. The most beneficial option should then reveal itself to you.
I wish you all the best with the decision you have before you. And in answer to your question - ideally, one shouldn't be attached to anything. But, until we become enlightened, we will have to work with our own delusions and attachments.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”
- Cormac McCarthy, The Road
Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
