I'm scared he might find out! What should I do?

Okay so there is this guy who I liked in the 11th grade... I thought he liked me so I decided to too. To be honest this whole situation is my fault๐Ÿ’€๐Ÿ˜… because I catch feelings so fast. So I'm in 12th grade now and he has left my school. He still has friends at the school. I was telling my friend about how I liked him (which I don't) just to make my ex jealous ๐Ÿ’€๐Ÿ˜…. I guess it backed fired on me because people think I like him which I don't and I had to try to cover it up by saying I like this other guy I met on Snapchat. Today, one of his good friends said that she knows I like him and again I tried covering it up. Now I'm afraid he may find out. Any advice?
