i am in colege and theere is this girl i have a crush on. Whenever i sit in the library i our eyes meet and she turns away quickly. I saw her pointing me out to her friends. She has this one friend, whenever i see them together, her friend smiles at the girl when they see me. All my friends told me to talk to the girl. I ask for her name and we had a lil convo. I ask if she had a bf and she said she has one and said do i have a gf and i was like i wouldnt be tlkn to u if i had a gf and she was like awwwwwww. all my girlfriends said she playing hard to get.I am confuse since she said she had a bf, what should i do any advice and does she like me and trying to fake that she has a bf
