Simple answer! Chance with my crush? Should I take the risk?

-We haven't hung out yet but we're pretty good friends.. any ideas about what to do about it?

-We walk together to some classes/after school & wait with our friends for the buses after school

-Almost allll of his friends are girls, & they all hang out, but they are also kinda my friends and they don't have feelings for him

-I used to be 90% sure he was gay but found out he used to have a girlfriend last year

-He compliments me a lottt! :)

-We are of similar attractiveness, intelligence, same type of humor, etc.

-He asked me for my # first! But recently he has kind of sucked at texting

-I used to talk to him about my other crush before I liked him... :/

-We're in high school, he's a year younger

-I told him he was adorable!

-We've had really deep conversations

I feel like he might treat a lot of girls like he treats me but I'm not sure. Is it better to stay "just friends" with him or take a risk and either be successful or make things awkward?

What is your guess with my chance with my crush? (%)
