Chrissie Hynde claims that she wrote this song for/and about a lonely fan, but I think she's fibbing; she wrote this for Ray Davies of The Kinks. Whatever, it's beautiful song and I'm glad that she gets credit for songwriting. I never saw the original Pretenders before half of them died, but I did see the second incarnation, The Pretenders, and the treat was that she was playing her hometown of Akron, Ohio. Some co-workers and I drove over from Cleveland to see them in 1984.
To me, the song is about letting go of a special someone you can't have today, but maybe tomorrow or someday.

Added: The electric version with the original band members from the good old MTV days:
This is a new series on MTV. Teenagers or post-teens are recalling their most outstanding teenage story. All of the stories are set to cartoons with elements provided as the oration develops accommodating changes as they go, thus the girl and a woman together at the end of a sofa that elongates off screen to allow for another woman not previously mentioned. The stories are great and so are the cartoons.
