I definitely don't want to discourage you from having high standards about who you date: You have a right to be picky! Lots of girls get to 18 without having boyfriends for that very reason.

It could be, however, that you have some unrealistic expectations. Sometimes (pretty often, actually) people build up almost super-human ideas of their crushes that then proceed to fall apart when the guy starts doing regular human things--like showing interest.

Who knows if that's you. But I recommend maybe trying to push on through that tricky moment when you seem to lose interest and into a more real situation of actually getting to know the guy. So the sparkle is suddenly gone...maybe go out with him anyway without a lot of expectations, even just once?

The key is not to put a lot of pressure on the situation, not to count on perfection. There will probably always be something that bugs you about this guy or that guy, but maybe sometimes there will just as much (or more) that you like!

In any case, your note is insightful enough to suggest that you know you're capable of being happy with or without a boyfriend--another key ingredient for getting through this kind of thing without a lot of trouble.
