Saw this movie about 15 years ago on HBO or Cinemax or Showtime. It involved a man and his wife who go to the Middle East (I think). She has affairs with several men and once she had to walk through a crowded market of men who all new that she was heading to her lover. He ends up making her give up a ring…her wedding ring I think. He also makes her sleep with a younger man instead of him.

The husband and wife end up separating. They run into each other at dinner and he ends up assaulting her in the restroom.

Maybe "the sheltering sky"
