The quote can be interpreted to mean that true love in marriage is not a fleeting emotion, but rather a lasting, deepening mutual respect and affection that grows over the years. The essence of the statement is that, over time, a husband gradually learns not only to experience romantic emotions but also to keep his wife "in his heart" in a profound way—that is, to cherish, value, and understand her on a deeper level. This is demonstrated by the fact that love in a mature marriage is based not so much on the initial passionate feelings, but on accumulated experience, the art of forgiveness, mutual support, and a shared responsibility for each other's happiness. As noted in one of the sources, “the expression ‘I love my wife as much as on our wedding day’ is not entirely accurate; after many years, a husband should love his wife even more than on the day of their wedding,” which emphasizes the idea that true feelings only become stronger and deeper with time (source: 1746_8729.txt).
