You new wife is not obligated to pay your child support. When you have a change in circumstance such as a loss of a job, you would need to file a Request for Order to lower your child support payment.
This new order would take into account the income of your ex as well as your own lack of income (you may get unemployment insurance which would be calculated as income) and a new child support order would go into effect.
