Well. Ball's in the husband's court. Send the vids to himself and dump her ass, or let it slide because of "love" or some other bullshit. Even without the videos, sounds like a paternity test would also vindicate him.
The art is fire. But the story is tragic... the wife is so broken and dumb that not only she does all that with the other man but she keeps the videos in her unlocked phone... the husband is so naive that until he saw that picture on her phone he never suspected anything.. and the bull is so pathetic that he needs to cling on to her just to feel powerful and relevant...
