How can I stop feeling like this?

Its going to be hard but ditch him ignore him when you see him act like you don't know him. He's just using you and you know it but you just need a guy to like you for. Put on some normal clothes what ever you feel good in. And don't pay atten. to him I know they're may be tons of guys that like you but your so busy paying atten. to that one guy who is just using you your missing out on they guys that like you for you! That's what's important right?
