My wife had to go through a lot of this with her mom.
I was the first guy she ever brought home. I think she had given up on her daughter ever finding stable love.
She's a good caring person, but also EXTREMELY trad and old-fashioned.
So she told me, RIGHT IN FRONT of her daughter, "You're the man, you have to put her on a diet and make her slim down!"
Good thing she was confident in her body and had my support.
We talked about it and she understood her mom was just concerned about her. "Normal girls" aren't "supposed" to literally quadruple in size and become so massive they take up two seats on the train and need help standing back up. So mom assumed she was helping her "little" girl out.
But mom realized her girl was happier, healthier, and lovelier than ever in her life as she kept gaining weight. So she gave in and accepted the fact that she was the proud parent of a super obese lady, and give her love.
