This quote is saying that in order to have a happy marriage, it is not enough to just be in love. In order to make the marriage last, there should also be a genuine friendship and liking for each other. This means that even if two people love each other a lot, they still need to be able to be friends and enjoy each other’s company. This friendship is more important than just being in love because it creates a healthy, lasting bond between the two people. In a nutshell, a good marriage requires more than just being in love; it requires genuine friendship, respect and liking for each other.
