Liking my bestfriend

So like me and my bestfriend hang out alot, like he's always over my house and I'm at his. But recently whenever I go somewhere with him people think we go out and his mom keeps asking me why we aren't together, even my other friends grandma said somethin about it when we dropped her off and like I have some feelings for him but he confuses me because he gives me little hints like he likes me but i don't know. I'm just confused and don't know what to do. Any tips?
