Idk what to do With this girl I like?

I really like this girl and iv known her for about a month. We can act normal aroun each other and iv hanged out with her alot of times. We talk on the phone for about 2 hours each time. Idk what to do though, I'm pretty sure she doesn't like me but I'm also not to sure. Idk if I should keep being friends with her and then I'll get over her later on or should I tell her but risk our friendship? If you can help ThankYou!!!
