Crush problem, a bit long, is this love, boys and girlss i need ur help, please please please?

Theres this girl that ever since i told her i liked her, she stopped talking to me in class but we always talk, chat, text each other with she knowing that i like her, and me i have been so shy to talk to her at school ever since i told her i like her, so for conclusion at school we dont talk but at home we always talk to each other so i asked why she doesnt use to talk to me at school and she says nothing, then i told her that am shy to talk to her at school, den she says den dont say anything and shun, then i call her two hours later and she now says if i use to be shy to talk to her then why did i call her, then i said i dont use to be shy talking to u on the phone den she says talk to me in class tomorrow and i say yes but tomorrow reachs and i still dont talk to her becos of shyness, then on monday was my birhthday, to my surprise this girl that dont use to talk to me at school buys me a present for my birthday, i already new the present was for me through my classmates, but she was acting really shy to just come and say happy birthday and give me the present, then finally she comes up to me shyly and gives me the present and says happy birthday and walks quickly away, but i dont really get it, that same day in clas, after that we did not still talk, and two of her friends birthday was on the same week with mine but she did not give them anything, just between us, it was her mother who insisted on buying that gift for her to give to me, presently we still dont talk at school but we always call, chat, and text each other. And like i saud she already knows i like her so does she like me
