Responding to her "freudian" slip in saying I love you?

Okay, so...

I am recently divorced and have been dating this girl and it is going SOOOOO awesome...We have been together for a while...we spend time together daily...hours together.

Today, as I was getting out of her car, we got into a comfortable moment where when I was getting out of the car, she said "I love you..." so quickly and almost randomly that it took me by surprise. She said it so quickly and 'uninterrupted' that I know it felt natural to her... But, as soon as she realized it, she backtracked quickly to cover it up.

Later on, I asked her about it since she quickly covered it up...and she said it was a "freudian slip...and was too early". Knowing she felt extremely awkward, I called her later that evening and told her it was okay and not to worry about it...On the phone she said, "lets just put it under the rug for now and you can bring it up later."

Now, I feel a bit pressured to follow-up on it...I kind of feel like if I DON'T respond to it that I will disrespect her feelings. I feel like love is 'in the making', but I do not feel like I am ready to actually say those words YET.

What do you think? Should I say anything about it at all? Or what? Thanks!
