Zsa Zsa Gabor is battling through her recovery but still very much has the will to live, her husband, Prince Frederic von Anhalt, exclusively tells ET.

The 99-year-old actress was hospitalized earlier this month, after she developed a lung infection from a feeding tube she had installed a few years ago. Frederic says Zsa Zsa has to change her feeding tube in the beginning of March.

"She is fighting right now and she wants to move on. She wants to live," Frederic, 72, says. "She squeezes my hand, she kisses. She is drinking water, she has ice cream. She wants to move on. People don't want to move on -- they give up, they totally give up, [but] she wants to move on."

"She never told me, 'Let me go,' or, 'I don't want to live anymore,' things like that -- like people do when they get to an age like that," he continues. "She never did it. Her mother did it but she never did it. So we keep going and see what happens. The main thing that we are watching is that we don't have any pain, you know? She has no pain at all."

Frederic -- who's been married to Zsa Zsa since 1986 -- says the legendary socialite is currently at home recovering, but the process has been difficult given her age.

"This is a struggle, you can see it in her face," he says. "The blood pressure goes up and down. We have to check it and then give her all the medication to quiet her down."

"We do the best, she is in a very good environment," he adds. "We take good care of her, but that is all we can do, you know? We entertain her. The only medicine we can give is entertainment. So, entertainment, keeping her comfortable -- that is all we can do. And we have to wait and see."

Another way Frederic is keeping his wife's spirits up is by focusing on the positive.

"She is talking to me, but I don't think she is aware. Because I told everybody there is no bad news in the bedroom," he explains. "We don't talk about any sickness in the bedroom -- only positive things. If you talk about hospital and doctors and things like that, you are out. We keep everything positive, she doesn't know."

"I don't [tell her everything] because if I tell her something negative, she is a target for strokes," he further explains. " ... I can't tell her what is going on because her blood pressure is so high, she is going to be very nervous. And you know, when the blood pressure is high, they cannot operate, they can't do anything."

And though Zsa Zsa just turned 99 on Feb. 6, Frederic already knows how he wants to celebrate should his wife live to be 100.

"We are going to make a big party," he shares. "I mean, how many times do you get to a 100? So, we are going to have a big party and we are going to celebrate it. Hopefully she is better, she is healthier."

"I hope we can celebrate her 100th birthday in our house, and she lives on like her mother did," he adds. "Her mother was 103."
