QUESTION::THIS GIRL IS PRETTY CUTE?

She would do things like talk to me a lot and find me in a room and come over and talk and text me and randomly call me and we'd do hw together and each lunch together and she would call me to ask me to eat dinner with her, but i tink she has a boyfriend becuase i saw them holding hands and these girls were saying that they were together. and i'd be like "howe're u doing with xxx?" and she'd be like "fine." so what does this mean does she like me??
