I shared my drink with a male friend (who I like) and we didn't share the straw and we spend a lot of time alone when we meet up. Is he interested?

We're family friends and when our families meet we spend a lot of time together

Talking or watching movies etc

But I'm not quite sure how he feels about me

Am I just a friend or more than that
