Wow, how messed up does this gal gotta be... steal your adoptive mothers husband, and make him your own? Not to mention the fact the guys old enough to be her grandfather to boot....
I agree that she's messed up, but she didn't steal him, he forced her. Who knows how long before it was made public that he was forcing himself on his adopted daughter. I figure this attitude that he is in complete control of the "relationship" with dismissal of any argument she has probably started long before she was ever an adult.
Sick bastard.
