The couple had a dream wedding in 2011, two years after they met. Four years later, Sarah claims she found a love letter stashed away in her husband's work bag where he'd made reference to the lead character Christian Grey from the erotic romance novel, Fifty Shades.

She said her husband in the letter had praised his mistress for being amazing before talking about their future together.

Mrs. Williams, who is a mother of three, is now using Facebook to sell all the items used for her wedding which produced one child from the union. The items include her diamante encrusted tiara, her rings and the £1,700 designer dress she wore on her big day.

"We had a wonderful wedding day and a great honeymoon in Scotland. We married two years after we first met and I thought we were going to be together for the rest of our lives.

"But in December 2015 I was innocently looking for a screwdriver which I thought was in his work bag when I came across his love letter.

"I was heartbroken. It was all about how amazing this woman was, how excited he was about the future with her and how it was the first of many birthdays they'd spend together.

"He had signed the letter with, "your Mr. Grey" and it was clear he was having a full blown affair, " the nursery worker told Daily Mail.

Her husband allegedly admitted he'd had an affair with another woman after she confronted him. She threw him out of their house afterwards and they have been separated since.

After filing for divorce, Mrs. Williams decided to get rid of everything that reminded of her crashed marriage - and make some cash out of it while doing so.

"On our big day in 2011 we were surrounded by our closest family and friends, I had the most amazing dress and I felt great in it.

"I just hope that the next bride to wear my Justin Alexander dress has better luck in marriage than I did.

"It's a perfect white dress with sequin detail; I paid £1,700 for it as well so it wasn't cheap.

"I suppose when you're so excited about getting married paying a lot for your dress seems worthwhile, “she told the newspaper.

Daily Mail reports that they reached out to Mr. William but couldn't get a response from him.
