As a Capricorn, you long for a steady, supportive relationship. As a Sagittarius, he loves his freedom. Beyond your sun signs, there are many astrological factors (both in your individual charts, and in how they relate to each other) that determine just how much potential your relationship will or will not have. For years I was very much in love with someone who came in and out of my life a number of times. It wasn't until I compared our charts that I was able to understood where the attraction between us came from -- and why we are, ultimately, very incompatible. Through this, I was finally able to stop thinking something would ultimately come of this relationship and move on. A chart comparison will help you know what to do.
