So why did they break up?

She can blame all her breakups on career but plenty of performers have family lives. She likes change. And he's a serial monogamist. Recipe for disaster in the end. But lots of sparks.

DING DING DING!!!
This is basically it, sure they had all the other problems that were mentioned on the first page-- jealousies, working together in the same band, being together 24/7, etc-- but I've always believed that this was the big thing.
Stevie was never going to end up with anyone. She was always going to be a "free spirit", not tied down by anyone or anything except her songs.
And I think that's even more obvious when considering the fact that Stevie never again had another real, proper, long-term relationship. She had lots of boyfriends for short periods of time, lots of affairs, but nothing long-lasting again. Lindsey had long-term relationship after long-term relationship. They had a very strong, combustible, but strong musical and physical chemistry that carried them through several years together with a lot of great music and drama coming out of it.
