How to tell if she likes me?

I asked this girl out but she said no.were still friends tho. (this is where it gets confusing). Before I liked the girl I asked out I had liked her friend first. After I got rejected her friend talked to me a bunch. Everytime I see her she looks at me and says hi even if I don't notice her. If I'm walkin down the hall shell pretend to hit me but in a friendly way. (they both sit across from me ony bus) on my bus she will look at me a bunch or talk to me. Sit with me. Draw on my face and when I get off the bus she will smack me. Does she like me? Ps I like her alot
