A British woman who donated a kidney to her spouse now wants it back after discovering he cheated on her with a friend during her recovery.

Samantha Lamb, 41, married her husband, Andy, in 2007 and gave him one of her kidneys a few years later when he became ill and needed a transplant, UPI reported.

Their marriage fell apart after rumors of his infidelity.

Now Samantha Lamb wants her kidney back.

"I can't believe he now has a second chance to live to see his grandchildren grow up," she told The Mirror. "I would definitely go through the operation again -- but I wouldn’t give the kidney to him. I hate him. If I could I'd take it back and give it someone else. Obviously I don't want people to be put off putting their names on the organ donor list. But all I want from him is his name on the divorce papers."

Although the other woman has admitted to the affair, Andy Lamb denies he cheated on his wife.

He claims he was helping the friend train her dog.
