Search Results: rejecting a guy

This guy approached me when he already knew his female friend for about a year. I rejected him and a few months later they are a couple. Did he at the time consider me a plan B or backup for her or was she the consolation prize?

And that he isn‘t really interested in getting to know her but feels entitled to her affection because he doesn’t think she is very desirable?
A guy tried to make eye contact with me which I ignored on two occasions out of insecurity because I considered him too handsome and smart for me. All of his friends in college knew that he had a crush on me. When he saw me in college a few months later he quickly rushed out of the room. I overheard him say to a friend of his „she probably thinks she is all that“ about me.

Does his behaviour indicate that he thinks I’m not desirable enough to be picky or why does he get so angry at me? I understand that one gets frustrated when rejected but if I admired someone I wouldn’t be mad just frustrated and very sad.
