Please help with this?

so there's a dance coming up called the sadie hawkins dance ( girls ask guys) and there's a girl that i want to ask me and shes a german foreign exchange student, we were talking about the dance. and she started asking questions about it and asked if anybody has asked me so far and i said no, but then she asked what kind of dancing there is and i said dirty dancing and there's some people that dance normally and she said shed ask me but she doesn't wanna dirty dance. at this point we were going our separate ways to cl and i said to her we could just dance normally and she said okay ill think about it and we'll talk more about it tomorrow. what should i do? should i just ask her? or should i just let her decide? i really like this girl and don't know what to do? please help?
