I have stood by a couple of friends over the years that went through really tough divorces. When you have children and the divorce is mostly forced on you it is very tough. It does funny things, as the article says. I told my friend once, with more insight than I realized at the time, something like this: “this will break you or make you something of a philosopher.” To that end I like the Stoics. A lot is out of our control. Figure out what is in your control and do your best with them (Dichotomy of control). It’s a good starting point. Sorry your family must experience this.
