Swear to love your wife and love you all your life, not just talk. What does it mean?

Is to show your partner your attitude towards this relationship. When the other party says that he will love his wife and you for the rest of his life, he is not just talking casually, but showing his attitude towards the two partnerships, not only responsible for his own feelings, but also for the future of the whole family. A loving wife means that a husband loves his wife very much. Two people respect each other like guests, and only have eyes for each other.
