What is when a guy asks why did you choose me?

When a guy asks why did you choose me, it could mean:

1. He is curious about your feelings towards him and wants to know why you are interested in him.

2. He might be insecure and unsure about his qualities and wants reassurance that he is a good catch.

3. He could be looking for validation for his own ego and wants to hear compliments from you.

If you are in a relationship with him, it might be a good opportunity to express your affection towards him and highlight the qualities that you admire in him. However, if you are not interested in continuing the relationship, you should be honest and upfront without giving false hopes.
