Follow divorce laws in your state and divorce him. Looks like one of you has to leave and be living apart for a year, so I'd get working on that ASAP.
Assuming your husband has a conditional, 2 year greencard, it's going to be up to him to provide what is required to remove conditions. So, either he has to be in a bonafide relationship or he can file to remove conditions with divorce waiver. If he chooses neither, he'll be put into removal proceedings.
