He may have a number of reasons, but chances are the main one will be that he doesnít find you pretty enough. Like it or not, most of us go by appearances, and the first appearance makes all the difference. So make it a point to look presentable all the time. That doesnít mean that you need to doll yourself up each day. Just be neat and tidy and pay attention to how you look.
But if itís not your looks, then it could be that he feels that youíre just not smart enough. Of course, it is quite impossible for anybody to draw a conclusion of a personís intelligence level in just a few minutes. So if heís jumped to that conclusion at the first meeting itself, too bad for him. He hasnít really given himself time to know you better. Consider it his loss.
Then, thereís a chance that heís already committed to somebody else. Now thatís a valid reason, and you can do little about it. Donít try to woo him away. Chances are youíll fall flat on your face.
Another reason for his disinterest in you could be that heís just not interested in starting something. Yes, there are many guys out there whoíre probably recovering from a bad relationship. So let them be. Donít force yourself. Hopefully youíll meet him again when heís ready.
Finally, one last --- but not least --- reason for him not liking you: he may be gay.
