Tell him ... Im sorry but i dont have feelings for u anymore !x
You should tell him your sense.
Give him the it not you it me routine......
So, why you worry, just tell him...
Tell him directly that u don't like him.
U should just say IM SORRY BUT I DONT THINK THAT WE ARE RIGHT FOR EACH OTHER hope that helps :)
I think you should just sort of ignore him, but not completely. Just enough for him to get your message.
Tell Him I Don't Think We Are Clicking.. It Looks Like You Are Not My Type.. You Are Special In Your Own Way And You Would Make A Great Boyfriend To A Girl Just Not Me
