is a dragon & a rabbit can grow old together?

I was born in the year of the dragon and planning to marry a man who is born during the year of the rabbit. Is it a good idea? We are compatible with so many things and shares ideas together..My previous relationship who was born during the year of the Goat failed.I am Aries & he was Leo..they said,we are supposed to be perfect couple but we dont share same interest & incompatible in almost everything.Now i met a man whom i think im going to grow old with and he feels the same.Im 38 & he is 51.should i marry him?
