What I think the lyricist is saying here is that as people struggle through their own demons and are preoccupied with their own wants and desires, they neglect and try best to navigate in their love relationship. Sometimes all they can do is be lovers, not forever, but "just for the day". This lack of permanence is especially difficult for women. She continues that a lot can be lost over time, hair turns grey and feelings wither. So she ends by praying that such couples spend less time focusing on what went wrong in the past. She rather ironically concludes that still not all is lost, and that the two should value each other, enjoy each other, even if just for the day.
