Girl's mad at me, what should I do?

I've been talking to her for a few days and she said she likes me, shes been wanting to hangout but we never got the opportunity to. I've heard that she likes somebody else but she never mentions him or seems to talk to him. I asked her who she likes and she said nobody, and then was asking if she could come over and I so no because I was mad that she didnt like me. Then I texted her calling her fake and she said "k f**k you" and I asked why she doesnt like me anymore and she said "because i didnt know if it was you since you were with people." Later that night I texted her and she texted back saying "hey?" and then I tried talking to her but she 'k'ed me. I asked why she keeps 'k'ing me and she said "cause" and didn't text back. What should I do? Should I text her today? I like her a lot so help /:
