Girls make you upset?

Okay, I really started to liek this girl and she was ya know a "hoe" but that didn't bother me at all, I still never gave up than she would tell me that she likes my best friend and that made me flip out and tell her I didn't wanna talk to her anymore but now after nto talking to her for about 3 days I want her to call me or txt me so bad, how do I explain to her why it makes me mad and how I can get her to forgive me?
