Plutarch on Suspicion

“Julius Cæsar divorced his wife Pompeia, but declared at the trial that he knew nothing of what was alleged against her and Clodius. When asked why, in that case, he had divorced her, he replied: "Because I would have the chastity of my wife clear even of suspicion."”

“As to Cæsar, when he was called upon, he gave no testimony against Clodius, nor did he affirm that he was certain of any injury done to his bed. He only said, "He had divorced Pompeia because the wife of Cæsar ought not only to be clear of such a crime, but of the very suspicion of it."”
