Do NOT under any circumstances tell her you love her so much! This is a turn off and a complete anti-thesis of challenge and the concept of non-neediness--which are traits a man should have to keep a woman's love.
If you're really crazy for her, chances are she already know it. She could read it on you. Just treat her right. If you're patient enough, if she feels the same she'll express this first. And this is the only time that you should tell her that you love her. But never before.
It's better if she does the adoring first because this is a sign that she's ready to accept your love.
