Stalker! Just kidding

So theres this guy, and it's obvious that he likes me! He tries to trip me, always comes over and talks with me, and he won't stop texting me!!! I don't like him back, and it's nearing Valentines Day and I think he's gonna ask me out! But I obviously will tell him no, but I'll feel bad for him! Oh well, this happens all the time in middle school, but it's the first time it's happened to me when I don't like the guy back!
