...is living with someone who doesn't eat healthy at all. My boyfriend, blessed with great skinny genetics, can eat whatever he wants. Makes me sick when I see him put down multiple Big Macs

and still have a six-pack.
He has this philosophy that "you can eat whatever you want as long as you exercise". Not like that for me, unfortunately. It's annoying and frustrating.
I love him more than anything, but his unhealthy eating habits rub off on me and I put on weight because of it. I don't want to blame him, it's not his fault. He just doesn't understand why losing weight is so difficult for me.
Sincerely,
Sick and tired of my boyfriend being skinnier than I am
