Some small positives there. You seemed to have caught her at one of her vulnerable moments, enjoy it. I don't think it was bad dring form to say the ILY comment, after all she brought it up.
Remember she just heard you, she is listening. She is going to deny it at first, but she definitely heard you. It may not pay off now, but trust that it will help in the future. Every positive thing you do that touches her heart will first have a negative and even angry response. That isn't necessarily a bad thing, as long as your intent was good it most likely will be recognized as long as you are sincere.
