I like to pick fights and argue with the girl I like? Should I stop?

[myself]

So I'm 16 and the girl I like is also 16. First I would like to say that yes I am very much OBSESSED with her. She has made it very clear to me that she hates me and thinks I'm ugly but I could careless as long as I get to be with her. Okay so I figured that if I can't have her love than hate is the next best thing because although she doesn't like me I at least get to be with her. So I would go up to her and I would just find anything to start an argument over and one time I ever slapped her in the face and made her cry and I felt really sad for her because I know I was being selfish. But part of me actually got turned on by seeing her cry and the fact that it was because of me I liked it even more. I think I should stop but I am also scared to because then I would't have an excuse to "be with her." Truth be told I would rather be cuddling her and showing her my fun side and hold hands with her and go on a picnic and make out with her. I don't know what to do anymore.
