How do you turn him down?

La
Ok this guy says he likes me. The deal is...he's the kind of guy to like everyone. But he says he's liked me for a long time. I gave him 3 chances and he blew them all. He says that all the other girls just want sex. But I know he has asked these girls for sex-begged is more like it. He's like "maybe we could be something. We could take it slow" and "I've found the perfect girl😘" I don't wanna hurt his feelings or get in a fight. But I will not date him. What are some great friend-zoning techniques that will help me get away?
