how do I get a guy to stop liking me?

[RaNdOm]

Next time your with him, make it clear that your not interested by talking about the guy you like. Or you could try something that I always do, suggest hooking him up with one of your friends! Everytime a guy likes me and I don't like him back, I'm always like "You want me to hook you up?" and if he's desperate, he'll say yes lol. Or next time he does something that indicates he likes you, just reject it. For example, Him: Your soo gorgeous, if we were to go out, id never let you go!
You: Um we wouldn't go out lol
I know it seems mean, but you got to let him know or he's not gonna leave you alone! Or you could just wait until he asks you out, and kindly say "No sorry, I like someone else" or you could lie and say "I already have a boyfriend"
Good luck!
