Insurance selling husband who cheated.....

Dear Dr Heartache...
My husband sells insurance for a big insurance company. The premiums he collects from hard-working people is a sin/ A SIN I tell you. Yes, they pay multiplied millions of dollars to buy insurance many of them will never use. It is a crime, a sin. I have lost all respect for him since I see him as a thief and a robber.
Anyway he recently became involved romantically with one of his clients. I am shocked that he would do this, yet am a bit relieved. Now she can put up with his robbery of innocent insurance victims.
What shall I do? Shall I laugh? Cry? Or shall I throw a big party for them? I'm a bit confused.
