She kissed me and now i can't think clearly. How do i deal with this?

She kissed me and called me beautiful and now i can't think about anything else. We're friends and she is just someone whos always been open about everything and never held back. Every time i see her shes flirty with me and it makes things even harder to figure out. I feel like i enjoy that kinda attention when i see her but i hate it when i don't. She even acts this way toward me in class which makes things almost unbearable. Even when i try to talk to her she'll say something that'll get me all flustered and then i can't. How do i deal with this? I don't even know if shes joking with me since she hasn't mentioned her orientation nor her feelings directly
