"However in a book that I own, which is by the way unauthorized, it states this: "Though the video to the song would appear cryptic and refer to situation beyond a relationship problem, the lyrics were romantic and direct, Axl suppurating "so if you want to love me then darlin don't refrain." This was an admittance that he required love as much as anyone and he felt together (with Stephanie the subject of the song) he and his 'perfect woman' could still find a way. 'Cause nothin lasts forever even cold November rain".
(At the book, not you - was it The Band that Time Forgot, by any chance?)
Most of NR was written in the early 80s. Axl stated during the 1990 Howard Stern interview that his relationship with Erin had helped him to finish it. It has fuck all to do with SS.
In the video, the chick who is played by SS but is really based on EE commits suicide, as others have said. Del James' story Without You is about a rockstar and his beloved, those characters are based on Axl and Erin and the trilogy is loosely based on the story.
