Honestly, it doesn't matter. If you love someone, just go for it! Don't worry about starsigns. Do you think that if you were a Cancer and your mother were a Capricorn and a magazine told her that you weren't a good match she'd disown you? Of course not! She loves you! Don't worry about what the stars say. Follow your heart.
It depends on other aspects of your natal chart. I'm a Sagittarius, and my most compatible sign is Scorpio, my moon sign. Sun signs, what you seem to be focused on, are only part of the overall scheme of things.
To break it down a little:
Ascendant - self projection
Sun - ego
Moon - emotions
Mercury - mind
Mars - physical energy
Venus - sexuality and/or love
The above are your personal planets/aspects. The other four are more or less generational planets. Each planet has both a sign and a degree. Who you're most compatible to is dependent upon how their signs pair up with yours geometrically.
The ascendant is calculated by determining where the planets were on the minute you were born. You need both birthplace and time to check on it. In a nutshell, it signifies how others see you, as opposed to the Sun sign, which reflects how you see yourself.
