This is a great resource. It's full of red flags to watch for when starting a relationship, what tactics abusive men use, how to get yourself out of those relationships, and it clarifies a lot of misconceptions about abuse and what constitutes abuse. It goes into depth about the reasons men abuse women - and it's mostly to do with his own fundamental value system, which is very very difficult to change. It's over 20 years old, so there is some outdated language here, but the majority of the book holds up well.
