Divorcing a Narcissist
If your spouse is a Narcissist, your divorce and beyond will be difficult.
If you understand how and why your narcissistic spouse is acting towards you, the pain will be a bit less, but have no misunderstanding that if you have a child together, it is basically a life of turmoil.
Be glad you escaped when you did, as your healing can start. A good book for your understanding and healing is "Surviving the Storm: Strategies and Realities when Divorcing a Narcissist" by Richard Skerritt.
