If life throws bad stuff at you, throw it back & move on
There is nothing more painful than watching your wife, girlfriend, sister, mother, father, friend or other people you care for being victimised by a narcissist or toxic person.
Mental abuse is just as bad as physical abuse, it is probably worse because mental abuse is multi generational.
If you know your loved one is being abused but do or say nothing about it, YOU ARE AS BAD as the abuser. You will tell lies to protect them, you cannot be trusted EVER.
