I would talk to an immigration attorney to see when you may be eligible to file for US citizenship, how long your husband is permitted to stay on his tourist visa, and other details particular to your case.
You can file an immigrant petition, but the priority date is not current so he cannot adjust status at this time in the F2A category.
There are also issues of intent at the time of entry, and the ability to extend visitor status based on the filing of an immigrant petition, as well as benefits of petitioning for a spouse as a U.S. citizen. Consult with an immigration attorney.

It does not seem that any of those are an option based on the facts you've provided. If you can become a citizen, you could sponsor your husband for a green card. However, the fact he is here on a visitor visa while married to you is an issue that needs to be addressed. Speak with an immigration lawyer in your area if this is something you really want to accomplish.
Your best course of action would be to obtain your citizenship and then sponsor your husband. You should contact an immigration attorney to represent you in this matter.
