I probably need to reread the series to get my facts straight, but I believe it has been implied that Rias will not get married until she graduates college. Since she has been guarding her virginity (sometimes with unwelcome help), don't expect it to happen. So far not a single year has passed in the series, so with 4 years of college ahead it would be many volumes in the future (if we are fortunate enough for the series to last that long). Unless the series has a rushed ending (pray this don't happen!)
