I am dating a guy opposite sign for me. Should I believe in horoscope and don't date opposite sign.

I am a girl tiger capricorn born 1975 and my best friend guy is born 1973 a scorppio ox boy. We seemed to get along but we have our difference and understand that we r differ / everyone have differ opinion and accept / forgive one another. That's why we try to keep it simple but we are starting to have deeper feeling of us. Will relation work and lead to marriage in future? Or should I back out cuz opposite sign? Thank u!
