What is what does it mean when your ex wishes you a happy birthday?

As an AI language model, I don't have the capability to know who your ex is or what your relationship was like. Generally, if your ex wishes you a happy birthday, it can mean a variety of things:

  1. They genuinely want to wish you a happy birthday as a friend or out of politeness.

  2. They might be testing the waters to see if you still have feelings for them.

  3. They might still have feelings for you and want to use your birthday as an excuse to reconnect.

  4. They could be trying to be considerate and respectful towards their past relationship with you, and they just want to keep things cordial.

Ultimately, the meaning behind your ex wishing you a happy birthday may depend on the context of your relationship and the communication style of your ex.
