In need of advice!!

To start this off, I’m just a teenager in need of advice for her stupid boy problems. The thing is I don’t want the boy...I’ve known this guy for a few years but we really have gotten closer this year (considering that we had multiple classes together). Each day, we talk and I get to learn more and more about him as a person. A few months ago in the middle of a conversation with him, I felt like I was developing some feelings for him but I just pushed it away because I thought it was just a small feeling. Nothing big or serious. I’ve been trying to put it off although, “romantic feelings” have been growing ever since then which is irritating because I don’t want that. Him and I have a good bond as friends. I don’t want anything more with him and I know for a fact that he just sees me as a friend. In conclusion, I have no hope or desire for a relationship with him yet these feelings grow more and more as I talk to him. This may sound dumb but ... how do you stop this lol...
