Fielder-Civil 'disappointed' by Winehouse

Amy Winehouse's jailed husband has written an emotional letter to his parents detailing his "disappointment" at his wife's recent behaviour.

Lawyers for Fielder-Civil, jailed in the UK for causing actual bodily harm and perverting the course of justice, filed papers in January in a bid to bring the couple's turbulent 20-month marriage to an end.

The move was said to be sparked by reports linking Winehouse to former rugby player Joshua Bowman during her current sunshine break in the Caribbean - but the pair has denied they were romantically involved, with the singer vowing to salvage her relationship with her husband.

Fielder-Civil has now revealed his reasons behind his decision to break-off his relationship with the star, blaming Winehouse for talking about their sex life and allegedly cheating on him while he has been behind bars.

The letter, obtained by British tabloid the News of the World, reads: "Does anyone deserve this kind of treatment? Am I that bad? Amy's words and actions have disappointed me a lot.

"The comment on my ability in the bedroom has caused a lot of humour among my fellow inmates. I must try harder with my next girlfriend!

"It would be all too easy to get into a war of words. The impulse to retaliate is strong but the need to act with dignity and respect is a must.

"I've taken everything on the chin and had my character assassinated but I've got nothing to prove to anyone. I know what I'm made of. I've made mistakes and I've been punished. In short, I want to be left alone."

Fielder-Civil married the 'Back To Black' star in Miami, Florida in 2007.
