How to get over someone...?

I've had this tiny little thing for a close friend of mine for a little over 2 years. Shes a really close friend and we've been together for a while and I just never brought up the...feelings...I have for her. The main reason is, lately shes been questioning her sexuality and me being the female I am, I didnt want to confuse her on it even more...so I kept silent. But just a few hours ago she told me about a girl she finds attractive and is considering asking her out. I dont wanna be in the way of her so I've decided to try to get rid of whatever it is I feel...but i dont exactly know how
