Is it bad when a guy gets jealous of you when he doesn't know you?

[Miranda Cole]

I don't know him. We're freshmen. Everyone knows him, but me. Every time I see him, he'll look at me or won't look at me. Him and I were walking in the hallway( he was w/ his friends) and my guy friend called my name, so I ran to him and he gave me a mean glare. I added him on Facebook and he accepted my friend request in less than a minute. Literally.(I have tons of mutual friends with him).He was acting weird and when he saw me, he tried to act normal. He kept staring at me and he(his friends) were near my locker and he said that someone smelled good( it was me). I got my hair straightened and when I saw him, he gave me a happy look, but he didn't smile. Now when he sees me, he'll either stare and look away or go near me. Today, he snapped his head towards me and gave me a happy look. In the hallways, he always goes in my personal space.
