My Dh uses The 'I don't drink or smoke, food is my only enjoyment/crutch'
Losing weight is 90% diet by the way so you don't really have to go gym.
I'm on the other side of this.
My Dh is my soul mate, he was honestly made for me and I'd never leave him (unless he met another women) no one can make me laugh like him and he is just awsome - but he has put a lot of weight on to the point when folk thst havnt seen him for a while are shocked. His lovely face is hidden by his extra weight and he looks nine month pregnant. - I'm not joking.
His hip is really bad due to his weight, he isn't getting picked for his beloved sports team anymore and he is breathing out of his arse going up stairs. He is tired all the time and I'm scared to death he is going to have a heart attack and leave me and my two girls that adore him.
We talk about healthy eating, I donit with him, I even cook him healthy meals and take them to work for him but after a few days he is back to drinking Coke and eating shit. Or he will say he hadn't eaten all day so makes an obscenely high plate of food. It's revolting.
I don't fancy him any more and I don't really want to make love to him and it makes me feel really sad because I love him so much and will never leave because of it.
I also feel a little resentment because of I'm being honest I didn't choose to go out with some one this fat/big and after every baby ive had I've worked hard to shift the extra weight.
I wish you luck op I really do but you can't blame him for you putting food in your mouth.
