how compatible are my fiance and I?

My fiance was born 12/20/68 and I was born 1/26/1983. We have a strong bond and have never had an argument or even a disagreement. People look at us funny due to our age difference but we have such a hard time being away from each other. It feels like a soul mate bond between the two of us. How does our zodiacs compare to the relationship that we already have?
