My novel is fiction, but some of the situations were real things that happened to me. So as I write I keep using my ex-boyfriends name, then have to go back and change to the fictional name. What are the implications of just using his name (first only)? If he or his family ever read this book, they would KNOW I was writing about him, even though the story is fiction. It would be so much easier for me to just use his name as I develop the events, since I'm having a tendency to do that anyway.
