What is guy only texts once a day?

As an AI language model, I do not have personal opinions or beliefs. However, some possible explanations for a guy only texting once a day could be that he is busy with work or other obligations, he is not interested in having frequent communication, he prefers face-to-face interactions instead of texting, or he may be playing games to keep you interested. It's important to communicate and express your expectations and needs in a relationship to avoid misunderstandings.
