Love is a Virtue

"Love in the full sense of the word is a virtue, not just an emotion, and still less a mere excitement of the senses. This virtue produced in the will and has at its disposal the resources of the will's spiritual potential...Love as a virtue is oriented by the will towards the value of the person." (p. 123, Love & Responsibility, Wojtyla)

It is virtuous to love. When I looked up virtue, I discovered it is 'moral excellence.' It is foundational for moral goodness. In other words, it's good for us and others. That's why it's a virtue, as recognized and valued by the world. It's the way we were created to be.
