As the child to parents who have gone through a VERY messy divorce, I can tell you that it takes a tole. It takes a toll on the family, the children, the parents, the grandparents, etc...
Sometimes it affects you in ways you are not even aware of.
I tend to not deal with emotions well, so I kind of numb myself when it comes to pain or trauma. Which isn't very healthy I've learned over the years.
When I was young, 5 years old when my parents officially divorced, I thought those were the hardest times of my life; and they were at the time. Little did I know that, unfortunately, there were many more tough times ahead.
