Why It’s Good If He’s Friends With His Ex Wife
They have shared friends
If the two were married for a while, then they likely have common friends. That’s fairly normal of couples. If they want to maintain those friendships, then the two of them need to maintain some base level of friendship themselves so they don’t make life a living hell for their shared friends. If he’s friends with his ex for the sake of a shared friend group, that means he cares about how his actions affect other people.
