I tried typing this into Google, but it returned 20 pages of "My wife gained weight and I don't love her. How can I convince her to start an eating disorder?" FFS the West.
Comrades, I wish to fuck that my gf gaining a few kilos was even in my top ten list of problems right now. I tell her that's she's fine. We're getting older, and we both put on a few kilos. I try to be supportive, and just let her feel comfortable with the new reality. It's like a major stressor for her. I guess some of her workmates and relatives have made comments. I tell her to tell those people to tell me. What kind of person comments on another person's appearance?
Just a final rant. Both me and me gf work sorta stressful office jobs, and we both end up doing a lot of overtime. Stress, anxiety, and a lack of time contribute to a less than ideal health situation. I know IRL a few venture capitalist types that spend hours in the gym everyday, but they're the worst humans imaginable. My gf comes from a working class background, and she's one of the kindest people I know. I don't mean to shame anyone that loves the gym, but spending adequate time on fitness isn't super easy in late stage capitalism.
Anyhow, if any of you comment on anyone's weight ever, I will literally claw your face.
The whole message from OP is that she should not feel shame for it, not that OP wants to help her lose weight. Flipping from "no you're absolutely fine the way you are, this is mostly outside our control" to "hey lets go for walks" kinda undermines the sincerity of "you are fine the way you are", when heard through the ears of someone insecure about their weight. OP literally said they are both putting in overtime at high-stress jobs and don't have time to exercise much. It's a sensitive subject and should be treated very carefully to avoid making the stress worse.
I'm not saying that they should or shouldn't pursue exercise, or that their weight is totally unchangeable, but OP didn't ask for diet/exercise tips, he just ranted about the people causing her stress (the ones making comments primarily, along with a generally misogynist and fatphobic society)
