Moving is really an emotional and stressful event to anyone. Without enough preparation, your move could trigger a conflict or misunderstanding with your wife or husband.
You might be moving because one of you was offered a good position or probably because one of you has a better opportunity in the other state. You need to remember that you are not the only one who will move, your better half and your kids, if you have, are also moving with you. Your wife or husband might have a good job from where you are currently living right; moving to another place might call for a resignation from his or her dream job. This could encourage conflicts and discussions.
When you move, you need to explain to your family why there is a need for you and the family to move to another place. Discuss with them the advantages of your move that the whole family will benefit. Provide them some scenarios on what will happen if you will not move, and if you will move.
You can do some research on what available job is currently being offered in the new place for you and your wife or husband. If you have kids, assure them that they will be going to a better school and in a friendlier community where they could also establish new friends and groups.
The secret to a smooth move with your family is to consider their feelings. It will give you more option on how to convince them why there is a need for you and the whole family to move.
