Would you please post the paragraph numbers? I cannot find those quotes in the Catechism. Thanks in advance!

In our marriage class, we learned that “submission” means, “under (the same) mission.” So that in submitting to her husband’s authority, the woman is trusting her husband to take responsibility and to lead her (and any children) in their shared mission of family. It takes a lot of trust in God, as well. If her husband goes against the mission by sinning, and/or doing serious harm to the family, she is not to follow him in that, but to gently and respectfully encourage him to return to the mission.
A wife is to follow her husband (except in sin). However, keep in mind that doesn’t mean he gets to “order her around” like a bully or a tyrant and expect her to obey. He is to love her “as Christ loved the Church,” so this is not saying the husband gets free reign to do whatever he wants–he should do what is best for his marriage.
This means he needs also to take his wife’s feelings, perspective, and knowledge into account when making decisions that affect the family–he should not typically be making important decisions without consulting his wife (not for her permission, but for her perspective). He should make the best decision he can for the family and generally take responsibility for the outcome. The wife should accept his decision, even if she does not agree with it (again, assuming there’s nothing immoral about it). The husband must be willing to sacrifice his own desires when necessary for the sake of his wife and family.
A husband also should generally trust his wife with his authority to make decisions that benefit the family, such as in the day-to-day running of the household and errands while he is working.
Marriage is a unique bond, a covenant. The “two become one” in a few different ways. One way is that they physically become one flesh in the marital act (and in the begetting of children). Another is that they come together and discuss their goals and future, and (hopefully) become of one mind, under the same “mission.” They generally should also share a household, expenses and income, struggles, successes, goals and responsibilities as “ours,” no longer as “yours” and “mine.” They are to put their union above all other relationships, to honor each other above others, and to put the other spouse ahead of even themselves in total self-giving. There are probably plenty more examples, but this post is already getting too long.
