how do I get over a girl?

Me and this girl talked as friends for 9 months, and eventually she figured out I was into her, she said that made her uncomfortable and we haven't talked since, that was 2 weeks ago.

she would be a horrible girlfriend tbh. she cheated on her ex twice, and I know she would probably do it again. but I can't shake her from my mind. I haven't been that close with a girl in years we knew everything about each other I think of her everyday it sucks
