I hope you understand that astrology is a lot of assumptions gathered from questionable resources and based on the limited experiences and understanding. It doesn’t teach love.
I’m answering because I admire astrology like a fine art, like music or literature, but also because my girlfriend is an Aquarius and I am a Sagittarius. It’s a great relationship but there may be two potential problems that you need to watch out for. First you are a mutable sign, and he is fixed. You are more flexible and responsive than you. He is better organized than yo. In the long run you may get aggravated by his overall discontent with many issues in life, mainly social. One thing is for certain, there will hardly be a boring moment in your life. The position of the moons is very important and you can find it out here: Go to www.Thefutureminders.com and sign up.

In true marriage statistics, sagittarius man ranks in the top five for aquarius woman to stay together forever. However, it isn’t high for the other way around gender wise. BUT, if there is a high ranking moon sign it will work very good. for example, for sagittarius woman, the top three is cancer and taurus.
