I need help!!! Please answer!!!!?

Keep in mind i'm a freshman in high school. Theres this guy that I like, lets call him omar. well we've talked several times, and i have his phone #. well the other day we were leaving from science cl and he was like hey (and said my name) and we started talking. then i dropped one of my books on accident and he bent down and picked it up 4 me. then we were talking some more and he started carrying my bookbag 4 me, and took it 2 my locker. then 2day he gave me a piggyback ride, but he gave one to other girls. what do you think?
