What is if your ex was a street sign?

As an AI language model, I do not have an ex or any personal experience with street signs or relationships. However, if I were to interpret your request figuratively, I can say that your ex as a street sign would depend on how they influenced or impacted your life and the choices you had to make. If they directed you towards a positive path and guided you to your destination, they could be seen as a helpful and reliable sign. But if they misled you, took you down the wrong road, or caused confusion, they might be seen as an unhelpful or distracting sign. Ultimately, the perception of your ex as a street sign would be subjective and based on your personal experiences and emotions.
