Does/Did he like me?

Well I'm 16, and I'm a year older than this guy I like at my school and he's really charming, cute and funny. In, around April, I noticed he started glancing, staring at me whenever he could. And I was doing it back. One time in the hallway he was staring at me when I was talking to my friends and I didn't notice until, o could feel someone stare at me (u know?) and he kept eye contact with me for a while.

He also stares at me when I walk down the stairs with my friend, and in class sometimes.

He stared at me and then my lips from his peripheral vision when I was putting on my lip balm, and he liked to walk EXTREMELY close to me when the bell rang for lunch.

Now its been nearly a week since I've been to school bc were on summer vacation
