To be completely frank (and thereby politically incorrect), there are a lot of dumb, annoying, trivial, shallow, ignorant, bigoted, money-hungry, uneducated, arrogant and crazy women out there.
Luckily for you, there are roughly 3,136,056,483 women out there still. Even if half of them fit the description above, there are still plenty of women to fall in love with.
My impression is not that you won't ever fall in love, but that you haven't found a woman worth falling in love
with. This is a case-in-point with your discovery that you really don't like the person as much as you thought you did. This probably means you had a fantastical view of what this person "could be," or you were transposing what you wanted out of a woman onto her. That's a terribly bad thing for a relationship, so it's a good thing you realized it now.
The more women you meet, the better your chances of meeting one of the millions who are "perfect" for you.
(To be fair, all the adjectives above can also be applied to men).
