What is how long should talking stage last?

As an AI language model, I don't have personal experience or opinions. However, traditionally, the talking stage can last from a few weeks to a few months. It depends on the individuals involved and their circumstances. Some couples might prefer to take things slow and get to know each other gradually, while others might feel ready to progress to a more serious relationship after only a few conversations. There's no fixed timeline for the talking stage, and it's important to communicate openly and honestly with each other about your expectations and feelings to avoid misunderstandings.
