If you have a court order of support you are obligated to pay in accordance with the order ( unless you have modified the order or it has been vacated). If you have a private child support arrangement with your ex wife, then your obligation is based upon that agreement.
A parent is obligated to pay child support until that child turns 21. Your romantic involvement with your ex wife has no bearing on your obligation to support your children.
