embarrassing situation involving my crush😬

So the other day I decided that I was gonna be bold and give my crush a note that said I think they’re cute (he had previously called me cute the year before and so I figured he liked me)...I did,and right after he went to his friends and tried to figure out who it was. he thought that someone had passed a note to me which I then had passed to him. so eventually he figured out it was me and ever since then,complete silence. he hasn’t said a word to me and won’t even look me in the eyes. this is confusing and sounds stupid,but I was actually kinda proud of myself for being bold and now it’s all just turned awkward and idk what to do :’( we sit right next to eachother and I can just feel the tension it’s horrible.
