Took

He knows where she found her "lovers" the rapist.

He was drugged, kidnapped, and held. She was a party to the events. All criminal charges. Yes his life would change, she would be in jail, he would be divorced. The assholes would be in prison. He could move on and out of there. Or he could do what many have done before. Since they all think he knows nothing all of them could have "fatal accidents" over time. The loving wife in particular once her insurance is increased. That is also a suitable ending.
