Now if you ex wife loses her job after this agreement, will I be forced to pay child support. And what if she moves out of state

I was granted joint legal and physical custody of my 2 children. The court ordered " that per agreement as placed on record, the parties shall be generally charged with the support and maintenance of minor children; and further ordered that the court will retain jurisdiction over the minor children. On record with the divorce papers I have the children about 208 days and she has them about 156 with an odd day out there.
