Guys; I need your advice?

There‘s thus guy at school and about 1 year ago I was pretty sure he liked me. After that I kinda stopped liking him and he as well stopped showing me as much affection as before. But now he‘s back to doing things he did back when he liked me and I caught hin staring a couple of times.. (I looked at him and he was already looking sorta thing)
And also something weird: He always asks me weird questions that are (a lot of times) out of context just like veeryy random questions. And he‘s always smiling when he looks at me/when we talk.
Sooo.. opinions are welcome, don‘t hold back:))
