I highly doubt that. She's way too merciless to do that. She's the type to slowly stab your heart with a rusty, dull, chipped knife that has been left in nitrogen for 4 days and was dunked in alcohol. I know that that's not scientifically impossible, but just think of the feeling. She doesn't do win backs and dumps. She makes them believe they're in charge, they're highly important, and their plans are coming together. Then she rips away at those delusions and stabs them where they fear most, and she does it slowly and calculatingly, so that they have no choice but to watch their world crumble around them with the suffocating helplessness of a deer stuck in headlights.
That's her method of payment.
I don't understand why people think that her becoming skinny has ANYTHING to do with the husband. Regardless of whether you like or dislike the fact that she isn't still chubby, she definitely isn't doing it to make the husband fall for her. Making the cheating bastard fall back in love with her has NEVER been her goal or the outcome in any of the stories. Everytime so far she's made them regret by taking everything away from them (the emperor lost his life, the actor lost his fame, the vampire because human and ended up poor and miserable). The reason any of them tried to get her back were ONLY because they wanted the things they lost, never because she suddenly became desirable to them. So debate whether or not she should have gotten skinny all you want, but lets not make the mistake of painting it as something she did to appeal to some man.
