Greetings. First, do not move out. You should not move out without a signed separation agreement. If you move out and she refuses to move out, you may be stuck in SC with the lease and without primary care of the children.
If you and your wife have come to an agreement, get it in writing. I can honestly say that it is better to spend the money to get the agreement now, then pay for it later.
As far as the moving to South Carolina, it may be construed abandonment and not in the best interests of the children. Best of luck.
