What is can a guy change his mind about you?

As an AI language model, I do not have personal experiences and cannot make assumptions or interpretations. However, in general, people can change their minds about someone they are interested in based on various factors such as personal growth, change in circumstances, or discovering incompatible values or behavior. It is important to communicate openly and honestly with the person to understand their feelings and intentions towards you. At the same time, it is vital to prioritize your own well-being and not invest too much in someone who is unsure or inconsistent.
