She should divorce you immediately. She deserves far better than a liar who faked it.
"Exactly what I wanted" eh? 
Who wants to bet you're a pain in the ass? Who wants to bet, 10-1 odds, that you treat her badly, get on her nerves, nag her, argue with her, and generally treat her like crap?
Replace her with sex robot is my advice. 
You made a promise, and had no intention of keeping it.
That makes you the problem, not her, so do her a favour and get out of her way.
Lucky for her she hasn't come down with cancer, lost her job, or gotten herself hit by a truck, isn't it. 
She simply committed the HORRENDOUS crime of getting fat before she got old, and you're having a tantrum. Because like most men, you don't actually give a crap about anybody or anything other than yourself.
Instead of congratulating yourself on yourself, ask around and find out how people really see you, because guaranteed it'll be very different from how you see yourself
She deserves better, here's hoping she finds it.
