What is the most heartless thing you have ever heard?

There is nothing more heartless than that, he said. It's okay to get a divorce, but you can't break off the "friend" relationship with her. Another sentence, from now on I will die outside and will not come to beg you or my son. I just laughed. I wonder what is there about me that makes him resentful like this? Fortunately, I had friends who enlightened me, otherwise my outlook on life would have been completely overturned by them, and I would no longer be able to face life.
