There is a difference between mental and heart/emotional. When you get into an argument with your parent or child, it is heart/emotional. When you wrestle with homework questions or work, it is mental. There is a difference. Survivability. Relationships do get severed. Not always by choice. Sometimes out of necessity. It's strange how it works. A little leaven leavens the whole batch. - Holy Bible A 20 year relationship can be ruined with very little;... It's strange. The 'damage' is within when 'damage' is made. I do not have knowledge as to how the inwards 'heal' nor do I have knowledge as to how much time might be available. Imagine a sociopath or narcissist 'having field day' on your 20 year + relationship. Does the relationship, then, hang upon the sociopath/narcissist's' decisions?? Could it happen again? Trust.
