Sebastian was stunned, stunned that Aurora, her little wife had these thoughts all along since they got married, hearing Aurora saying all those things to him, he didn't know what to say nor what to do, he was stuck between his truth and her thoughts.
first, it was true, in some way it was true when Aurora said the fact that he cheated her, and that he had a mistress.. but at the same time, it was also false as since the day he got married to her, he hadn't talked to Rose.. nor even look for her or even asked about her, he completely decided to break up with her, but he never told her they should, so this confusion, again, was his fault and no one else's.
seeing the hurtful look in her eyes broke him apart, but wait a minute... in some point, she's like this because she's in pain, that he cheated her, that he had another woman behind her back... does this mean that, even after all these days... all this time, her hating him, pushing him away, she actually considered him as hers?
