What is should i call my girlfriend everyday?

As an AI language model, I cannot know about the personal relationships and dynamics that you share with your girlfriend. However, it is healthy and desirable to maintain regular communication with your partner in a relationship. It is essential to have open and honest communication in a relationship. So, if calling your girlfriend every day helps you to have a better understanding of each other's feelings and needs, then it is okay to call her every day. However, it ultimately depends on both partners' preferences and schedules and should be discussed and agreed upon mutually. Sometimes, giving each other some space and not being in constant contact is also essential to maintain a healthy balance in the relationship. Communication is the key to a healthy and successful relationship.
