Some creepy blokes don't like their wives losing weight. Might mean that the wife realises what a waste of space they've got leeching off them, so they encourage them to just have a little bit, it won't hurt, it's only fair that they should enjoy something, etc. In my twatty ex's case, I didn't want the big greasy fry up and decided to make myself beans on toast. The doorbell rang and when I went back into the kitchen, I found him carefully melting an entire block of butter into the beans. His excuse when I asked him what on earth he was doing was 'Oh, I was making them glossy for you' and he acted all hard done by when I refused to eat them, as I was ungrateful and picking on him when he was only helping me and being nice by cooking for me when I'd been so fussy already. There was also a lot of 'you don't need to lose any more', 'I love you how you are', 'why should I go without the things I like because you're not eating them' and so on. Had I had WLS, I'm certain he would have been blending up chocolate bars, cream and syrups into shakes, buying the greasiest, fattiest meals and doing everything he could to increase the calories I consumed. Once I'd realised what he was up to, I tried an experiment - I said I was thinking about taking up a gym membership when I'd lost a couple more pounds. He came home with ice cream that evening, a takeaway the next, wanted another fry up the following morning, then more ice cream, then cream cakes appeared in the fridge the next. And he turned his nose up at any suggestion for food that didn't involve frying, vast amounts of pasta and melted cheese or butter for the next fortnight.
Mr D genuinely doesn't mind either way whether I'm bigger or smaller. As long as I don't start ED behaviours, he cooks what I want how I want it. He came home with seabass fillets that he grilled to serve with boiled potato and salad a couple of days ago, even though he doesn't like wet fish. And he was about to pay for a gym membership at the gym I wanted to go to (it has a pool, so is far, far more expensive) when lockdown happened.
Men with a lot to lose from their wives realising they can do better without the dead weight are a thing in WL.
