Do i want her because shes like my friend?

Well I've been after my best friend for a couple years I've asked her out I've professed my love nothing worked. Anyway I rhought I was over it but reacently I was talking to her about someone I like and "I fell oh so hard for u after all" got sent now things are a bit awkward between us and I realized that the girl I like is just like my friend and I'm worried that its the only reason I like her
