Please don't give long responses, period.
let him catch you looking him over then shyly glance away (takes around 4 times for most guys to notice this). make it so you are accidentally in his line of view often, and smile when you see him. the idea is to bring yourself slowly into his reality. bump into him and say hi and smile shyly, find excuses to speak with him, pick on him for his taste in clothes (neg him). etc
Insult him and pretend you think he's worthless. If he tries to impress you, act annoyed that you found something you can appreciate about him. When he's really liking you, ask him why he hates you. Let yourself get lost in the moment so it's good, then get some space.
It takes a lot of effort to maintain a dysfunctional relationship.
BTW that won't make him fall in love, that's just how to get interested.
