The video, which has now gone viral, shows the married woman, called Nina, locked in a tight embrace with a man in a bar, the New York Post reported.
The video was posted on Reddit with an explanation that the husband had suspected his wife of cheating after a year and a half of marriage. He had apparently asked James, his best friend, to follow her and see what she was up to, having heard which bar she was going to that night.
After his fears were confirmed, the husband gave her a day to move out of the house.
The video has already gained almost 4000 comments, with most appalled at Nina's behavior. But some commentators criticized the men for trying to humiliate her online, or said James was wrong to getting involved.
