You would first need to marry. You could not qualify for an F-2 visa unless married to the F-1 status holder. Once married, you could apply for an F-2 visa but you will eventually either need to complete the home resident requirement or seek a waiver. You can read more about J-1 at http://myattorneyusa.com/j-1-student-visas-overview.
