I don't understand the "that she meant what I think she did" part:
I really hope... that she meant what I think she did.
Can it be paraphrased to clarify this?
Here is the fuller context:
My heart was beating so fast. I rolled over, I felt so... I don't know, nervous? After a minute she put her arm around me, and was so close, and whispered in my ear, "I really like you." I just nodded my head and I really hope she could tell. I really hope... that she meant what I think she did.
