What would he do if you got fat but didn't have a fat fetish?
I never understood people that get bent out of shape over their partner's size. So long as you are healthy and it's not causing any harm, it's dumb for him to be upset about it. This goes for weight loss and weight gain.
My question is, why does he have a problem with your size?
Miachu:
I don't get it either, imo you should love someone for what they are on the inside, not the out
And i spoke with him about it earlier. I didn't go well, ended up becoming a argument. He told me he doesn't know how to feel with the prospect of just watching me continue to get fatter and fatter, And doesn't know if he's finding me physically attractive atm or in the future, depending on who knows how Fat I get. It kinda hurt hearing him say that tbh. He said to me he doesn't just wanna sit there and watch me balloon, and how he misses the old me (Health and fitness obsessed me)
From where I sit, this sounds extremely toxic and controlling of him. Again, taking the fetish aspect out of it, it sounds like he's being extremely fatphobic. He's got some personal maturing to do, and I don't think you can help him with that.
Unfortunately, it seems you will have to make a choice. Will you lose weight to keep your boyfriend happy? Or will you keep gaining even if that means breaking up?
