Does my ex still like me?

Last friday, my ex broke up with me saying: I just don't have feelings for you anymore.

In the past week, he's done all of this.

-He's watch my best friend Chris (whom he hates) and I walk down the hallways.

-When we would go out, and I was in my health room and he was in his spanish room, we could see each other. just for fun (for the two days I have health) I decided to look at him. I see him staring right back at me, both of those two times!

-He's tried catching my eye a few times in band.

-He still wears the sweatshirt I gave him.

- When my friend angie told him," Well, I was talking to michelle today..." He asked," My michelle?" Apparently he still thinks I'm his?

- He said on the tuesday after we broke up, he was confused on his feelings of me.

Is he still into me?
