Not to be rude, but you must read, "He's Just Not that Into You", by Greg Berhardt. I wish that book had been around when I was 16. My life may be very different.
You did answer your own question. I f he was that interested he'd see you. "I'll take a pass". What is that about? He did not even make up an excuse.
I no longer waste time on men (or anyone) who is not respectful of my time or me. I have dropped "friends" who have cancelled one too many times, are excessively late, etc, Life is too short to waste on people who are selfish.
