Criticising and insulting the other side while communicating is another reason that leads to divorce.
You are so selfish.
Most couples circle the wagons when they come across with an insulting manner. Actually this is another way to blame the other side.

There is a high possibility that your relationship end up with divorce when you don't take resposibility and defend yourself everytime you argue.
