How do I get over her?

I feel you my man the girl I liked rejected me and is getting attention from some jerks cause she dresses slutty. I appreciated her in a different way. So now I see she is no good for me. So my point is that if you want to get over her, look for her bad qualities and talk to other girls (flirt). Also talk about your situation to some stranger. To teacher, boss, a bum, a guy from the park. Open yourself to someone who you are not so familiar with cause then you'll feel free know I'm sayin?
