What people didn't see even after my divorce me and my ex wife could easily communicate laugh and have a good time ?

I get it. People are wondering why, if you can be friends and talk and laugh together, what was so terrible that you couldn't stay together. 

Who cares?                                                                             

Some people will remain friendly after a divorce. I know divorced people who have a better relationship with each other than they did when they were married.

Is this a riddle? Okay, I give up... 

What people didn't see even after 

your divorce you and your ex wife 

could easily communicate laugh 

and have a good time?
