People are asking about other bruises or marks on the body. I don't think his domestic abuse MO was ongoing physical slapping and such. But he wanted her to shut up and had never learned to control his emotions. Gabby's "fault" is not being able to recognize the warning signs and not realizing that "love" doesn't conquer everything. Not that this was love. She wanted someone who shared her values and thought she had found him. Him? I think he wanted someone that could elevate his "life" status in people's eyes. Very much a Paul Snider.
