The fat wife, skinny husband is quite a common thing  Common doesn't make it normal. That says absolutely nothing.   Well, your theory could well be true, but I think it more likely that she is doing it to herself. She is an adult after all.  So is Tess Munster. So are all the people on the show My 600 Lb Life. They all have enablers, don't try and defend this fat cow. She's not a little fat, she's fucking disgusting. Someone is paying for these useless fuck to eat this much around the clock. If she was put out on her useless ass, she'd drop the weight real fast to hook herself another man, or, resort to another fetishist who buys her shit and feeds her. No, that's not "normal".
