Hey, good to hear from you again. As Lovebroken said, reading those e-mails would be many steps backwards. Yea, destructive narcissist are all too common. I've had the same experience throughout life and had to just rip then out of my life and some, such as family members, are near impossible to deal with since you can't just stop talking to them. The best solution I've come up with is just not caring what they say and do.
Maybe a better way to explain this is that, as a last resort, we un-invest in toxic people and use those un-invested resources to invest in non-toxic people and ourselves. Your time, your caring, your emotions, your heart. You take back all of that, have all those things for yourself, and have the freedom and ability to give those precious things to those who don't hurt you. It creates self-esteem, self respect, peace, reduces destructive patterns and demolishes the strength of people who are out to hurt you. It's not easy, and rarely can this be done immediately, but you're worth enough to not have to suffer because of others.
