Why does my crush act comfortable around me?

Anonymous
I have a crush on this teen guy, and when I talk to him he seems strangely comfortable and calm. He never used to be that way. He used to stare at me then look away, now he stares at me and doesn't care if I see him and he just holds eye contact. (I'm always staring at him first though, if that makes a difference.)

He used to avoid me completely, now it seems like he tries to run into me, but he still avoids me a little bit.

It goes in this sequence: stare>approach>avoid.

When he approaches me, he doesn't say anything. I say hi first then a polite goodbye, and he always talks when I'm finished.

He always says one word then walks away. He acts normal/friendly towards me, but I feel a little more respect.

-Before he approached me the other day, he looked down at the ground (I was looking at him) and he smiled to himself, but looked at me with a straight face.

-I've only heard it once, but my mom said that he was looking around for me, when I wasn't watching. He looked at my car, then around the area til he saw me.

Why does he act comfortable around me? Does he not like me? Why does he then avoid me?
