Have your mother ask her for you. I am sure she could set everything up for you.
1. Your too young to talk of love.
2. If you don't talk how do you know she loves you
3. If your talking then the asking out is easy.
4. Don't run before you can walk, Don't get over involved in what your head thinks. Plenty of time for that later.
