Joanne Bradley was sick of playing second fiddle to the First Division club and is filing for divorce.
The final straw came when husband Neil bought her some tasty Norwich underwear... as an anniversary present.
Joanne, 36, said during their nine-year marriage, Neil had:
Joanne, who lives in Manston, Kent, told the Sun: "There were three of us in our relationship - Neil, me and Norwich. And I came last.
Embarrassment
"When he came back with the knickers I went mad. He seemed to think they were sexy!
"Even our car was covered in a huge Norwich banner. Living in Kent it was a bit of an embarrassment."
But it was their 10-year-old son, Lee, who Joanne felt most sorry for.
"Neil bought him every club hat, shirt, scarf, mug and duvet," she explained. "And Lee didn't even support them!"
Neil's fixation with all things Norwich began as a child and he is now chairman of the East Kent Canaries' supporters' club.
"It has become like a drug to me," he confessed.
Or an overdose in Joanne's case.
