My 4 years guy friend called me bestie. Why?

He is a guy friend whom I known for 4 years plus. I likes him more than a friend. But we never talk about it. Now since I’m not getting any respond from him I’m avoiding myself to let him go and find someone who loves me. But now he tries to reach me out all of sudden. He calls me for dinner with his siblings, text me often. And now he address me as BESTIE!! He never address me in such way before this. What he is trying to say. I’m confused!
