WOW, I'd take a step back if I were you. Marriage is a pretty permanent thing and you're still young. Maybe dating for a few years first would be more prudent. This could just be the excitement of a new relationship, which can fade fast and leave a crappy relationship behind. Live your lives together before you make a lifelong commitment to someone you barely know.
That and you gotta at least hit it once or twice. You know, would you buy a car w/out taking it out for a test drive? Are you buying new or used?
