I must disagree somewhat with the other attorney's post. Yes, you should definitely secure a family lawyer to help you with the divorce and all the related issues, such as child support, division of assets, etc. However, the I-864 affidavit of support IS an enforceable contract. The sponsored immigrant, state government or federal government have the right to enforce this contract. It may not gain you much, since it only creates an obligation to support the sponsored immigrant at 125% of the poverty level.
I strongly advise consulting with an immigration attorney before filing any papers with immigration, particularly if the person for whom you are filing has any past negative immigration or criminal history and is in the United States. There is always a risk of removal from the United States.
If you are hoping to collect money from your husband in the form of support, the affidavit of support is not the right vehicle to do so.
Contact a family lawyer to discuss your case.
You cannot enforce the affidavit of support.
