Women have been doing this forever, since the dawn of time. My kids are 5 and 2 and she's still fat.  I can't change her.  She's the mother of my kids.  I won't break up my family, but I have lost virtually all of my romantic feelings toward her and at this point even if she got fit again I doubt I could ever love her the way I did when we got married.  I told her on the second date that if she ever got fat I'd stop loving her.  Her complete and total disregard for my feelings is infuriating. I also make tons of money and she's a stay at home mom.  I gave her exactly the life she wanted and she can't even be bothered to not stuff her face (secretly, while I'm asleep, I'm sure of it).  It's a level of betrayal at least as high as if I cheated on her, but if I ever did, she'd rape me in divorce court because she, like most fat wives, maintain state-sanctioned double standards (and chins).
