did she like me or not?

12th grade starts and about three days into school I see her walking with some guy. She looks at me for a like a second while she walks and then looks away. A few days later I'm at the mall and Im coming out and she's coming out and we saw each other and I looked away. I think she looked at me for like a second to two seconds. We never spoke or anything. I was at the schools office once and she was leaving the office and came back to get something else she forgot and stood right next to me, though she just looked straight ahead (if she liked me, why wouldn't she even look at me, right). Another time at the same office, I looked back to see the clock on the wall and she was sitting there looking in my direction. She then turned to her phone to text or something. Another time I'm at a starbucks line and after I plave my order, I notice she's next in line. She was however texting and decided to call someone instead of talking to me...anothertime I'm at the mall and I'm coming in and she's heading out with a friend and we both see each other, I look away like I don't care(though in my head I'm dying for her lol) and shw looks at me for like 0.5 to a full second. Anothertime at the same.mall duringb christmas she noticed me and looked at me for like 2 full seconds or maybe a little more.She put sappy stuff on her phone as well, saying stuff like how she had been thinking of someone lately and how she shouldnforget about him, or how there r plenty of fish in the sea. She even complained with some guy about how she was giving up on someone because that person never made an attempt to do something and she did all she could?Now, this girl is popular and last year she flirted with other guys and even approached them first when she though they were attractive( we had a class together, but again we never interacted)

On Twitter, she once complained about a person who never approached her and how she did all she could but he never did anything. She also retweeted a pic of a message saying how shes been thinking abut someone lately and how she needs to forget about that person...and she stated how scary that message was.

 My friend told me it was all coinscidence. That this girl couldn't have liked me. I mean, a super popular girl liking me but didn't approach me when she approached other dudes more attractive, wtf, right? 

I dont see her anymore since we both graduated but... do you think she liked me, yes or no and why do you think so?
