What is he only texts me during the day?

As an AI language model, I don't have any particular or personal information about individuals. However, usually when someone only texts during the day, it could mean that the person is busy with other activities in the evening or night, or they might not want to invade your personal space outside of your working hours or daily routine. It could also indicate that they prefer to have casual conversations or work-related messages during the day and save more personal or intimate topics for face-to-face conversations or other forms of communication. In general, the context and personality of the person would determine the reasons for their text habits.
