'The Preacher's Wife' airs Friday, November 5th, at 9pm/8c:

After serving time in jail and regaining custody of her children, Mary Winkler, who made headlines in March 2006 for killing her preacher husband and father of three daughters, sits down for an exclusive primetime interview with Dateline correspondent Keith Morrison, this Friday, Nov. 5. For the special two-hour report, Winkler speaks out about her husband's dark side, and reveals what drove her to end his life to protect hers and the lives of their daughters.

In March 2006, Matthew Winkler, known by his congregation as a pious preacher and loving father and husband, was found dead in his own bed in the small town of Selmer, Tennessee. Police searched for his wife and children for days, finally tracking them down in an Alabama town over 400 miles away. After she confessed to killing him, the trial of Mary Winkler appeared to be case closed, until she finally spoke up and revealed to the court the intensely private secrets of her husband's dark side.

In the interview with Morrison, Winkler explains the inner struggle she faced as a loyal wife who allegedly suffered severe mental and physical abuse at the hand of her husband. She says she is telling her story now to advise all the women who suffer the same type of abuse. "Ask for help….Know that someone will believe you, someone will help you. And you're not alone. I'm not leading by example. But I am leading out of regret."

Below are excerpts from the interview:

On accepting money from Natalee Holloway's family in exchange for the location of her remains
VAN DER SLOOT: I have had five years long that people have just been blaming me for something. And yeah, I have a lot of anger built up because of that also. And yeah, at one point I just thought that, OK, you know, "You keep insisting that you want to give me this money. I've already told a lot of different stories. I'll do it--I'll do it again." And yeah, I know it's very wrong--very wrong, what I did.

Why he told so many different stories about the disappearance of Natalee Holloway:
VAN DER SLOOT: There were--people were paying me to--paying me to--yeah, to make up stories, and I was really good at making up stories. Everybody keeps coming at you, asking you questions, asking you stuff and, you know, you don't know something, and finally you start to think, `OK, well...(censored by network)...you. If you--if you want something, then I'll tell you whatever you want to hear. Sure. I misused the situation for my own advantage and I feel bad about that. And if I could change that, I would take it back for sure.

On the impact his actions have had on his family
JORAN VAN DER SLOOT: For everything that happened since 2005, all the things said in the media and everything, I feel guilty for it, yeah.

VAN DER SLOOT: I was doing a lot of things that I shouldn't have been—I shouldn't have been doing, and mostly only going out all the night and sleeping all the day. I have always been very, how you call it, impulsive, always been--take action right away and make a decision immediately and not think about what the consequences are.
