You should reach the bed only by small steps. Don't say you love her if you don't feel anything to her. Choose the right moment of doing so. She, likes you very much, but the way to love is still long. She will be in shocking situation.
Love is very strong word.
Don't use it when not needed. They think she will jump to the bed right a way. Although she will try to show you her greetings, don't expect to much. She's just a girl, and if she is between younger then 16. If you like to write, write her love letters.
