OK i don't get this girl?

So there is this girl and i thought she like me. She would like always give me like 10 second hugs and always ask me to tex her she would ask me walk with her to cl ext.. But like when she is with a friend she sometimes ignores me or sometimes she doesn't. When she ask me to tex her she wont tex back or she tex's back 2 word responses. Why are girls soo complicated? What do you think?? What should i do?
