Kateryna said that when she looks at her husband now -- he was voted the most handsome man in Ukraine at one time -- she, too, sees him as a symbol of the country's suffering.
"I see that he's a man who's fighting for a cause," she said. "He says it's a small price to pay for what we're achieving in this country."
Though no plot has been proven against her husband's life, the couple believes the alleged poisoning can be traced to the highest levels of the government.
"It's the people in power, the people who don't want the system to change," said Kateryna.
And despite the fact that her family has received death threats, she and her children will stay by Yushchenko's side. It is the price they have to pay for democracy, she said.
"No, we're not leaving," she said. "We're a family. We have to be with our father at this time. I think that what gives him strength is coming home at the end of the day and seeing all his children."
