In 2007, Samantha and Andy Lamb of Ivybridge, Devon, England got married. Two years later, Andy had kidney failure and needed a transplant . . . or he'd die. So Samantha donated her kidney to save her husband's life.
Then, in August of 2012, Samantha says Andy CHEATED ON HER with one of her friends. So now . . . she wants her kidney BACK.
Samantha is now 41 and Andy is 45. She says she regrets donating her kidney and, quote, "I would definitely go through the operation again but I wouldn't give the kidney to him . . . [I'd] give it to someone else."
Andy says he DIDN'T cheat on Samantha . . . their marriage fell apart because they were always fighting and her family hated him.
Also, Andy says he's just friends with the woman Samantha thinks he cheated with. Quote, "I just helped train her dog." (UPI / Daily Mirror)
