Husband watching co workers old Porn

My husband was watching his co workers old porn. She is 22 but did porn at 18. I caught him watching videos of her naked topless. Even worse he text his friend telling him to watch her porn and she has the best boobs he’s ever seen and that he wished she’d show him blah blah. I have found screenshots of pictures of her naked. I am so hurt and angry. My husband is 46 by the way. Idk what to do...
