Did you advise CIC when you got married? (change in marital status on application)? Your application should have had your spouse on it, that would make your spouse part of the family class. If your spouse was not on the application, then you can not sponsor under the family class. The same is true for any dependent children.
As far as I can tell ( I am not an immigration lawyer, so please keep that in mind), you need to wait for the application to continue (because "You indicated on your sponsorship application that you wish to continue with its processing regardless of any ineligibility. As such, the Application for Permanent Residence for your relative(s) has been forwarded to a visa office abroad for consideration)." If the decision is not an approval, then you can appeal your application to sponsor.
Here is a case of appeal that won, that is similar to yours, as long as you can proved that you informed immigration of the change in your marital status:

Very disappointing news, I can appreciate. If I were you, I would be finding an immigration lawyer to advise you on what your options are and what steps you can take.
Best of luck.
