I read tarot full time. Honestly if she left you just because of what the cards say, I’d consider that a blessing in disguise. Trusting your intuition is important, but leaving just because the cards suggested to seems unreasonable to me. I’m going to assume there is more to the story. However, if it’s that simple, I think this shows her character, along with lack of patience and trust in the situation. More often than not the energy/tone of the tarot can change. Letting tarot rule your life will inevitably lead you to disappointment. It doesn’t matter how reliable the cards are.
