'Cause I really need to be taken care of...
This part just breaks my heart! It's like she's saying, "I can't take this anymore, I've been through so much and I need help." And BBT just loves her so much.
I also love that she decides to stay with him in the end. Even though it's disturbing to her that he withheld information (that he pretty much executed her husband), I think she realizes that he has completely changed his life, and together they can go forward and hopefully leave their dismal pasts behind.
