How to stop him liking me?
Wow, that’s tough and you’ve done everything right by trying to get him to stop liking you. I think at this point you have to just flat out tell him “I DON’T LIKE YOU!” and then tell him that if he can’t stop showing his emotions towards you and get over it, then you can’t really be his friend. That’s tough to do, but it has come to that point. Good Luck!
