You need to get the support order modified on the basis of the changed circumstances. You really need to work with an attorney to get this done. Many will provide low cost or no cost initial consultations and could tell you upfront an approximate amount your matter would cost to complete - maybe even take monthly payments.

I'd add that you should look to the original judgment that awarded your ex-wife spousal support. It may specify circumstances that would result in termination of support.
My responses to posts on AVVO are not legal advice, nor do they create an attorney-client relationship. In order to provide true (and reliable) legal advice, an attorney must be able to ask questions of the person seeking legal advice and to thus gather the appropriate information. In order for an attorney-client relationship to exist, you and I both have to agree the the terms of such an agreement.
