It's natural cos when I went to high school my friend was always really odd because she made new friends.

It's probably a huge mixture of 'stuff'... Jealousy / Still has some feelings for you / Feels awkward himself and is dealing with it in a typically bad way, etc, etc... People tend to push others away when they feel uncomfortable. I had a boyfriend for 19 months back when I was 16 and he STILL treats me like the plague NOW!! (He is now coming up for forty!!!!)

He might think he's not good or smart enough to be friends with someone who is in a better place of education.

Hope it helps. :)
