Your husband doens't realise it, but his own actions are what is making his anger worse.
He may feel frustrated with the quality of his marriage, but his affair, and the guilt that comes with it, is just feeding that anger into a frenzy... and making him increaasingly emotionally and physically ill, as well as the family he has abaondoned.
The solution is clear, to someone who isn't this angry, but from his perspective, he can see nothing but his own self-induced rage.
