Ah, but people do occasionally do seemingly-altruistic things, and by long experience, some of those are worth encouraging.

"Love" in English wears too many hats. C.S. Lewis' Four Loves does a good job explaining how the highest and best use of eros (which can be selfish) is to encourage agape (selfless love).

"The promise, made when I am in love and because I am in love, to be true to the beloved as long as I live, commits me to being true even if I cease to be in love."
