In a nutshell, if someone is making your life tough, manipulating you, and you keep getting sucked back in this book is for you. Basically, do not call, text, have as a friend on social media, reply to their messages at all. The exception is if you share children together and then only talk about your children, nothing else. Set up boundaries. I found this book a little harsh, but then again maybe that's why it was written for me and I picked it up because I think we can be friends but the reality is we were not there yet. If you think you may need this book, you probably do.
