Seeing spouses negatively is positive:

US research has shown that viewing our spouses more negatively over time can be positive."As we age,and become closer and more comfortable with one another,it could be that we are more able to express ourselves to each other.In other words,its possible that negativity is a normal aspect of close relationships that include a great deal of daily contact," said Kira Birditt,a research fellow at the University of Michigan Institute for Social Research (ISR)."While our relationships with children and best friends tend to become less negative as we age,we are more likely to see our spouses as irritating and demanding," he added.
