There are 3 tarot cards that can mean divorce. These are the Three of Swords, which heralds pain and separation; the Tower, which indicates an unexpected crisis; and the Five of Cups, which represents a change of partner.
However, tarot readings are highly personal and require a careful reading by a qualified professional. Some cards could talk about a positive outcome in one reading while representing an adverse scenario in another one. I recommend you seek guidance from an experienced psychic from the best sites for tarot readings.
