The 2008 attacks left more than160 people dead.
Faiza Outalha, of Morocco, and Daood Gilani, a Pakistani-American living in Chicago met in Pakistan four years ago and were married within one week.
Ms. Outalha says she didn't know that Gilani was also known as David Coleman Headley and that he had taken radical vows long before their wedding vows.
"It was love at first sight, you know, and we just married and, you know, it was so quick," Outalha told the I-Team.
Outalha says the man she loved had a hidden hatred. For the first time, she is unlocking the soul of terrorist – the woman who thought she was his soul mate.
"I'm covering my face right now, yes because I'm afraid that people really could look at, see my face and pursue me or come and try to harm me," she said.
In her first television interview by Skype from Morocco David Headley's wife told the I-Team that she quickly realized her husband was connected to Pakistan's most brutal terrorist organization and tried to warn local officials.
"I said something [was] wrong and I started imagining him the way he looks like, [one] blue eye, [one] brown eye, and the way he sometimes with a beard, sometimes without a beard. So I went to them and I then started saying stuff, I said he's going to bomb everything, he's a criminal, they didn't bother," said Outalha.
Then she claims to have come to the American embassy in Islamabad with the same warning: her husband was helping to plot a terrorist attack.
"How many us officials do you think you spoke to trying to convince them?" Chuck Goudie asked her.
"I went to U.S. authorities to help me out but then, they were like looking at me, oh, you are not a U.S. citizen and he is an American and we've got nothing to do with him. I was like shocked so I started saying, 'is he working with you, you are defending him,'" she said.
Years earlier, Headley had been a U.S. drug informant, but it is unclear whether American officials did anything with Faiza Outalha's information.
What is known is that on November 26th, 2008 teams of Pakistani terrorists raided several sites in Mumbai, India. When the bloody siege had ended, nearly 165 people were dead and hundreds more wounded.
"Some people think I'm the spy, the couples spy, you know, other people say, they hink I'm a terrorist," said Outalha.
That includes India's intelligence agency which would like to know her whereabouts.
She insists that she is not a terrorist, even though Headley scouted attack locations on video, while they were on their honeymoon and Headley entertained his terrorist handlers in their home.
"He betrayed me in every way, many lies, he's been lying to me, I mean the marriage, he fooled me to this marriage," said Outalha.
If Ms. Outalha now knows her husband is a terrorist, she is as certain that his alleged accomplice was not. Chicago travel agent Tahawwur Rana was convicted -- on Headley's testimony -- of aiding the terrorist organization.
"I don't believe that Rana is a bad person, personally, because all I heard about him is good things and he's a business man, he's not into any terror or killing or anything like that," said Outalha.
Rana has yet to be sentenced but could face up to 30 years in prison.
Headley pleaded guilty in exchange for no death sentence or extradition to India.
At this point, Headley is still married to two women including Ms. Outalha. She is trying to divorce him but finding it impossible to accomplish from Morocco, even though Headley's lawyer says Headley will sign divorce papers if she can get a lawyer to the United States to file them.
