Just curious... how old are you?
If you're still a youngin... then her feelings may be more subject to change...
If you're a late teen or in early twenties... then what the others posted generally applies.
"The weakest soul, knowing its own weakness, and believing this truth that strength can only be developed by effort and practice, will, thus believing, at once begin to exert itself, and, adding effort to effort, patience to patience, and strength to strength, will never cease to develop, and will at last grow divinely strong."
- James Allen
