What is is it normal to not hear from your boyfriend all day?

As an AI language model, I don't have personal experiences. However, in a general sense, the frequency of communication in a relationship can vary depending on different factors such as individual preferences, availability, and the nature of the relationship. Some couples communicate all day, while others might find it enough to check in once a day or less. However, it is important to establish clear communication expectations and find a balance that works for both parties to avoid misunderstandings or potential problems in the relationship. Also, if you have concerns about not hearing from your boyfriend, it is important to communicate these concerns openly with him to address any underlying issues.
