Replying to Problem

I posted something in a thread but didnt get much help so im gonna create my own thread.

ok bout 4 mon ago i started becoming friends with this girl b/c we liked eachother. we became best friends. and we always liked each other alot. so finally this past weekend i asked her out. she decided that she didnt want us to go out because she didnt want us to break up and not be friends anymore. she also said wat will change if we go out. (we already talk on the phone all the time, hang out) she said that just hooking up and shit isnt a good reason to go out. wat should i tell her to change her mind. (all i got before was to fuck her friends and family members)
