How about this, can everyone agree that this would be a good thing to say to her:

I have to tell you up front right now I'm starting to get feelings for you. I do not want you to treat me differently if you don't feel the same because I'm still at the stage where it's not too difficult to try getting over you. But if you want someone in your life that you don't have to wonder what girl he's with or if he'll ever lay a finger on you again, without a question I'd treat you the way a poor lovestruck dummy should treat the girl he admires most. But say so right now and I'll never bring it up again and the conversation is over for good.
