I have to wonder, if she declared her undying love for you, from the bottom of her heart, would you believe her? It seems a bit soon for her to have come that far. I think she is being honest with you (so you want to be ready to hear her answers before you ask her anything). Also, and this is important, you know that love is a decision. She has made that decision now, and is investing in your loving relationship. Now it can evolve to what you want it to be. Give it time. When this gets really frustrating, go have a chat with LL about patience!
