My wife is obese?

First off size 12 isn't obese. Secondly if your wife is comfortable and her weight is not causing any health risks she shouldn't have to lose any weight just because you want her to. However,if she does want to lose weight you have to be supportive. Saying she eats like a hippo is not being supportive, you're just being an asshole. Try going to the gym with her and help her out. Also do the excersices with her so she doesn't feel like you're her drill sargent. Encourage her to eat healthy, and find nurtious meals you both like. Don't be mean about what she eats either. Instead if saying "Do you really need to eat that." Say "I'm really in the mood for a salad. Do you want some? " Even if you feel like you don't need to be on a diet, it will be easier for her if you participate with her. So while she eats an apple for breakfast don't eat a breakfast burrito from McDonald's. It will just make her feel bad. Also, make excersing fun. Find something enjoyable that you can both do together.

Are you really that rude? First of all size 12 isn't that big idiot. You should have married her because of love, not lust. I'm surprised she even married you jacka**. If anything you should support her (no, this doesn't mean calling her a fat hippo) that is your wife just in case you forgot. I bet even a 12 year old has better sense than you do you douche bag.

Size 12 is not obese, maybe slightly overweight if anything. You can get a membership and join the gym with her.

How about you get over yourself and quit being such a jerk. If you can't love your wife because she gained a few pounds then you honestly aren't good enough for her. Marriage is about love and being with someone who makes you happy, not having trophy wife. I'm sure you aren't the hottest person.
