Well, mutahhir, I have to say, it always feels good when a guy falls for you. Girls pick up on that so much easier than guys seem to, so this girl most likely already knows how you feel. But it's always much nicer when the guy confirms that with words.

Tell her you like her. Often.
Of course, it's probably different there, but in the US, we don't particularly go into every relationship thinking it must end in marriage. That's a lot of pressure to put on a new relationship. If you like this girl, and she likes you, and you both enjoy each other's company, isn't that reason enough to continue seeing each other?
As far as the attraction factor, someone once told me that you won't date someone you are not attracted to for very long. Because if you like them, and want to continue to see them, you will discover things about the person that you
do find attractive.
*And I always enjoy getting a look into the male psyche- so beautiful and weird. Guys are much more complex and thoughtful than they are usually given credit for. So *lol* thank you.
Good luck.
