NO it's not her responsibility to pay for your child. I do suggest she keep her money separate from yours.
It's a pity you do no research before answering questions, Shawna. Because you just might be wrong, especially when you make blanket statements.
Q: In setting support under your State's guidelines, whose income is considered in addition to the NCP (e.g., new spouse's or child's)
A: New spouse's or child's income may only be considered by the court in a request for a deviation. The guidelines worksheets do not include any incomes other than the obligees and obligors.
