WENDY is confident her marriage will survive. "We're going through a bad spot at the moment, but it won't last," she says.

How nice, you might think, to find someone willing to work at making a relationship endure - until learning the "bad spot" is that husband David is serving eight years for trying to kill her.

Wendy believes he's innocent, despite a taped conversation in which David asks a friend to murder her, adding, "She's nothing to me".

She just laughed when her eldest son first played her the tape and continued to stand by David, letting him live in the matrimonial home while on bail before the trial.

Wendy says she's madly, not blindly, in love. "Nothing will ever part us again," she says. You could only sit in open-mouthed astonishment as Wendy told how she plans to stand by her man, hopefully not until her death them do part.

Others, like Joanne, in this documentary disagreed with her. She met Martin in her mother's pub in Hartlepool. He claimed to be an undercover agent in Northern Ireland, breaking down and crying as he recounted seeing his best friend get shot.

Joanne quit her job and left the area. She joined Martin living in a rundown area in a house without any furniture. He said his work meant he had to live in the community he was investigating. Ten months later, she discovered he'd been lying about being an undercover agent. "Love is blind. I chose what I wanted to see," she says with hindsight.

This film also demonstrated that some couples do live happily ever. Jon was smitten with Stephanie from the moment he saw her, but it was two years before she agreed to a date. She insisted on an old-fashioned courtship with no kissing, telling Jon that her uncle was very strict with her.

She seemed hesitant about committing herself to a relationship. Several years later, after he asked her to marry him, Jon found out why. Stephanie was a princess, who came from one of the wealthiest families in Ghana and was destined to be a queen.

"I wanted to be sure because I was going to give up everything I'd been taught to be if I married Jon," she explains.

They've been married 12 years, have five children and Stephanie doesn't regret becoming a commoner. "We could do with the servants though," she jokes.
