Are we incompatible?

i want to meet my matches on the zodiac, i am a rat !!
but they say ox,dragon and monkey are compatible...i have a girl i like
who is a dragon but that means were are both virgo's...due to the chinese year !!
does this mean we are incompatible because we are so familiar.
went out with virgo before and didnt work out,is there a clash.
and it says we should marry late in life..i am 38...she is 46....hhave we left it too late ?
