Identify a song from the nineties?

This song was on a CD that my son played in the car once when we were going somewhere in the late 1990s, perhaps 1999. He doesn’t remember it now by my description. He was about 13 at the time. The style was what I would call “soft rock”; I don’t know what it’s called now. It may have been a single male vocalist. The tone was solemn and sad.

The storyline of the song, which unfolds as the song progresses, is an affecting tragedy: two youngsters meet over ?spring break, and a few weeks later he’s forgotten her already, and she is facing pregnancy alone. A patterned refrain develops her isolation and despair—ending, I think, with her suicide—while he doesn’t remember her at all. I seem to recall a recurring image of the floor, but I don’t remember what part it played in the scene.

A title alone won’t click with me, nor will a group’s name. I may never have known them. I’d need a link to lyrics or a performance.
