[ Singles & Dating ] Open Question : She tries to make me jealous and makes out that i like her!?

Okay, theres this girl that i do like. But ive not made it obvious to anyone or her that i do like her. We talk on facebook for a long time. And shes really cool....But she tries to make me jealous by telling me that other boys keep on talking to her, and they want her number. She'd then ask me if im jealous!?...id say "ermmm,no" and shed say "wrong answer, omg dave" She also tells her friends that i always text her, and that i like her, ive only texted her once asking her to come to a houseparty. Why would she try to make me jealous? and why would she tell all her friends that i like her? :S Thanks for any help Cheers :D
