The man's action is irrational. He was looking for a way to send your friend away so that he could bring his new mistress. With two children, that's bad.
I see him coming back to apologize in future. He made a mistake and he will regret it.
I commend for standing by your friend and seeing her through such a difficult phase. Depression is not an easy phase in one's life.
My dear, j have been waiting for this apology from him since two years ago. Are sure he will still come 😃
