Lindsey Groves, 32, was 17 stone five years ago, and her husband, Alan, 41, had only ever known his wife to be overweight and insecure.
Mrs Groves, of Knutsford, Cheshire, finally found her confidence when she shed six stone last year, but Mr Groves became convinced his hot wife would leave him for a younger man.
Teetering on the brink of divorce, Mrs Groves had to resort to extreme measures to prove to her husband she loved him - so last year she remarried him.
Mrs Groves, a kitchen-assistant, said: “My diet nearly ended in divorce - my husband was convinced I would leave him for a new man when I slimmed down. I knew I had to prove to him that I loved him, so we remarried last year and that convinced him that he is still the only one for me.”
Mrs Groves struggled with her weight from a young age.
“I was always the biggest in my group of friends - even at primary school I stood out,” she said.
“I was a slightly tubby size 14 when I first met Alan in a local pub and we instantly hit it off - by 2001 we were married and had the first of our three children on the way.”
Shortly after giving birth to her youngest daughter, the mother of three weighed in at a whopping 17 stone.
On a typical day Mrs Groves lived on a calorific diet of junk food, crisps and chocolate bars.
Mrs Groves said: “I didn’t really eat three meals a day, I just grazed. I’d eat everything I could at all hours of the day. Alan always said the right thing - he loved me whatever size I was, but I was so self-conscious.
“I couldn’t bare to be touched by him, I hated the thought of him feeling all my fat through my clothes. The more I hated myself, the more I nagged Alan. I was certain he was going to leave me for someone else.”

Desperate to shift her belly, Mrs Groves signed up to a local slimming club in 2011. She finally lost six stone through diet and exercise.
She stuck to a strict diet eating Weetabix with semi-skimmed milk for breakfast, lean meat and vegetables for lunch and a pasta salad for dinner.
Mrs Groves stopped snacking between meals and shunned junk food in favour of fresh fruit and vegetables. She also started exercising, going to the gym for high intensity cardio classes three times a week.
“I was at the gym most days, and jogging on the others,” said Mrs Groves.
“I’ve swapped comfort eating for exercise. The pounds were quickly dropping off and before long I was a slim 11 stone. It was the best I’d ever looked.”
Finally proud to show off her slender figure, Mrs Groves started going out with friends more frequently.
But while she was on cloud nine, her marriage was entering a storm.
Mrs Groves said: “I was expecting Alan to be chuffed with his new hot wife, but if he was he certainly wasn’t showing it. He always seemed to be spoiling for a fight, accusing me of fancying other people.
“Every time I went out he’d throw me a snide comment about what I was wearing, or how many times I’d been out that week. I knew we couldn’t go on like that and I snapped, demanding to know what was going on in his head.
“That’s when he admitted that after 12 years of living with a wife without any confidence, he was struggling to adjust to the new me. He was convinced I was looking for a new man to go with my new body. Our marriage was on the brink of collapse - I was devastated.”
Mrs Groves decided to prove to her husband that, despite her new figure, she was still the same woman he married 13 years ago.
She asked him if he would marry her again.
Mrs Groves said: “It was a wonderful ceremony, we got married in a church in front of 60 friends and family.
“I was able to wear a proper wedding dress this time around - as at our first wedding I was too large.”
Mr Groves, a handy man, said: “After she lost weight Lindsey started to go out more. She found a new group of friends who she loved to socialise with, meanwhile I would have to stay at home to look after the kids.
“She had a gorgeous new look and fresh confidence, so I did worry she’d meet another man. But when Lindsey asked me to marry her again, I realised that she wanted to show off the fact that we’re still together and in love.
“When I saw her walk down the church aisle I was so proud to call her my wife. She looked beautiful, and I finally believed it was me she wanted.”
