Do you think your significant other is making you fat? Do you find that they “mistakenly” bring home your favorite fatty foods every time you try to go on a diet? Does it seem like, the more you try to lose weight, the more they want to go out to eat?
That may not just be your imagination. In situations like that, I would guess that your significant other is overweight as well. And, while they may not intentionally be trying to get you to gain weight, they probably are subconsciously. Some overweight people are very self-conscious of how they look, but they feel better about themselves if they are not the only one who has put on a few pounds. Your attempt to diet, however, is a stark reality for them that they are not as slim as they used to be. The response shows that they could use some emotional maturing, and counseling or coaching could help them.
