Most Helpful Guy
If I was married and my wife got up to a point where she was overweight but NOT obese/morbidly obese, I would remain married to her. If she reached the point of obesity, I could deal with it, although it would ruin my sex drive.
If she was to the point where she was morbidly obese (we're talking people who have a hard time walking), I couldn't remain married. I would feel like a caretaker at this point.
