Can I be honest?
What about if he simply did not like 'the sight' of you and did not have the courage to tell? So he just made some excuses.

In my opinion is as simple as that.

And btw, don't think that no one will like you. This depends a lot on the person that you are facing. Sometimes they do get a click, but you don't. Sometimes you do but he doesn't. Some other times the both of you get the click and that's what you are looking for
