Ha! Great question. I wrote a book called The Bum Magnet, which is NOT yet another book dissing men rather a woman's journey to figure out what's broken inside herself so she can make better choices in men. Now I would be lying if I sat up here and said that NONE of it is based on my past relationships. But what you do is exaggerate details and change names to protect the innocent (and guilty!) LOL I think all writers in some sense or another pull from their own experiences when they write stories. It's the humanity of our stories. It's what makes people connect. So, I think it's very cathartic but must be done with respect and a lot of imagination.
