Bianca felt naked before Adam, not physically but mentally. It was as if Adam could see her true nature, which she herself had tried to deny time and time again.
But now that Adam has made her confront her true nature, that of a selfish woman who is only out for herself, she has stopped making excuses.
She asked herself why she was even trying to be someone she is not. She has been cheating on her fiancé for over a year, and that poor idiot has no clue about it.
He is so blinded by love that he cannot even see the obvious signs of her infidelity throughout the year.
There might be some guilt inside Bianca for her husband, but what she really feels towards her fiancé is distaste. For the hard-working, dedicated, and simpleton her fiancé is, he doesn't act like how a man should act in her eyes.
