If you did not ask for spousal support at the time of divorce, you may be precluded from asking for it now. Child support is not meant to support the ex but rather to pay for the child's expenses, needs and health.  Your petition to ask for child support may backfire should you ask for it now because no doubt he will ask for an accounting and the court will ask what happened with the child support, as well.  Your best option is to meet with a divorce attorney, who can weigh the pros and cons with you about filing to amend the divorce decree.
