What is when a guy texts you goodnight and goodmorning?

If a guy is texting you goodnight and good morning regularly, it could be a sign that he is interested in you and wants to maintain communication with you throughout the day and night. It may also indicate that he cares about your well-being and wants to make sure you have a good night's sleep and start your day off well. However, it's important to remember that everyone has different communication styles and preferences, and texting habits alone cannot be relied upon to determine someone's level of interest or affection. Communication is key in developing a relationship, and it's important to have conversations with each other about how you like to stay in touch.
