H E L P!

So I’m a junior in high school and I really like this guy. We’ve been really close friends since I moved to Montana in 3rd grade, and I know I can tell him anything. One of my best friends hinted that I liked him and now he knows. His words were “Really?! I wasn’t expecting that!” And so now idk if he likes me or doesn’t, but i don’t have the slightest clue on what to do because I don’t want to ruin one of my favorite friendships. Please help!
