If your marriage ends in divorce, your conditional permanent resident status terminates on the date the divorce becomes final. At that time, you are no longer a permanent resident of the United States and you become ineligible to work or travel outside the United States, among other consequences.
You may file a waiver if you become victim of domestic violence, or you're divorce because your husband are in jail, etc. but this is a complicated matter, it's recommended that you should contact an experienced immigration attorney to assist you with the process.
