People are tense, stressed. You may say or do something that didn’t land right on the other person. Something you might normally say/do that doesn’t ruffle anything might bring negative responses in this time. Or your spouse may have.
Be quick to apologize. Explain your regret for having hurt them. Do not explain it away or minimize it or try to put it into perspective. Just apologize. Later, you can explain your perspective.
Be quick to forgive. Don’t hold onto the mis-statement or mis-deed. It is never a good idea, but especially in these day when there are real decisions to be made and you need a clear head and good synergy between you.
