Scare me off? That's a weird term. The only thing that would scare me is stalker like tendencies, and possibly a third nipple! ;)

There are certain qualities that bother me in prospective partners, but scaring me is pretty difficult. A lot of the ones previously mentioned fit, but my biggest one is fakeness. I can't stand someone who tries to be something they're not. Just be yourself. Fakeness is a surefire way to make me say nice knowing ya, and that's in ANY relationship.
