PM, unfortunately, radio stations get stuff wrong all the time. However, I am allowing myself to get more and more hopeful that this will happen!
CL, Stevie has never said that she dumped Don, as far as I know. It's unclear exactly who left whom there. I get the impression that he just kind of stopped sending the booty-call jet for her after the unplanned pregnancy and abortion took the shine off the rose for both of them - that there was no real breakup per se, just a breaking off of contact until it became obvious that it was over without the words ever having to be said. That's just speculation derived from reading a lot of interviews, though.
As for Joe, the breakup went down with her giving him an ultimatum, him giving her one in return, and the whole thing crumbling as a result. She left him because he wasn't willing to get serious, so if anything he broke her heart, not vice versa. He still acted like a douche by insulting her regularly for the next few years onstage and on radio programs, but unless I'm mistaken, that stopped when he sobered up in 1994/1995.
In fact, I don't think either guy has dissed her recently. Or did I miss something?
Stevie only speaks of Don and Joe in glowing terms. They are lucky she is so kind, generous, and forgiving, because they've both done her wrong.
What's past is past, though, and they're both better men now. Heck, in the case of Don, Stevie now calls him a close friend. According to her, he's one of the first people she called when she was in New York on September 11, 2001. That says a lot.
