Perhaps it is Robert Sheckley — A Ticket to Tranai. I remember some kind of stasis field and wife in it but I am not really sure if it is this story.
UPD: For example, here is reference in review:
"Why did his wife appear from a derrsin statis field at the touch of a red button"
You can read the whole story here. The following passage is the part you described:
"I loved you very much, Janna," he said softly.
"You didn't!" she shrilled, throwing back her head. "Just look at the way you treated me. You kept me around all day, every day, doing housework, cooking, sitting. Marvin, I could feel myself aging. Day after day, the same weary, stupid routine. And most of the time, when you came home, you were too tired to even notice me. All you could talk about was your stupid robots! I was being wasted, Marvin, wasted!"
It suddenly occurred to Goodman that his wife was unhinged. Very gently he said, "But, Janna, that's how life is. A husband and wife settle into a companionable situation. They age together side by side. It can't all be high spots--"
"But of course it can! Try to understand, Marvin. It can, on Tranai--for a woman!"
"It's impossible," Goodman said.
"On Tranai, a woman expects a life of enjoyment and pleasure. It's her right, just as men have their rights. She expects to come out of stasis and find a little party prepared, or a walk in the moonlight, or a swim, or a movie." She began to cry again. "But you were so smart. You had to change it. I should have known better than to trust a Terran."
The other man sighed and lighted a cigarette.
"I know you can't help being an alien, Marvin," Janna said. "But I do want you to understand. Love isn't everything. A woman must be practical, too. The way things were going, I would have been an old woman while all my friends were still young."
"Still young?" Goodman repeated blankly.
"Of course," the man said. "A woman doesn't age in the derrsin field."
"But the whole thing is ghastly," said Goodman. "My wife would still be a young woman when I was old.
"That's just when you would appreciate a young woman," Janna said.
"But how about you?" Goodman asked. "Would you appreciate an old man?"
"He still doesn't understand," the man said.
"Marvin, try. Isn't it clear yet? Throughout your life, you would have a young and beautiful woman whose only desire would be to please you. And when you died--don't look shocked, dear; everybody dies--when you died, I would still be young, and by law I'd inherit all your money."
"I'm beginning to see," Goodman said. "I suppose that's another accepted phase of Tranaian life--the wealthy young widow who can pursue her own pleasures."
"Naturally. In this way, everything is for the best for everybody. The man has a young wife whom he sees only when he wishes. He has his complete freedom and a nice home as well. The woman is relieved of all the dullness of ordinary living and, while she can still enjoy it, is well provided for."
