No, dependents actually don't work that way. Sorry to hear about your husband I know how stressful that can be. Your spouse can never be your dependent. A dependent is either a child under the age of 18 (24 if a full-time student) or a completely disabled relative.
For spouse, you file married filing joint which does give you a huge benefit over other filing status. Are you working now? You can claim another exemption or two to get more money out of your paycheck until he is able to find a job...
