When it comes to texting a girl you're interested in, it's important to find the right balance. According to this article, the frequency of texting should be based on the level of comfort and interaction established between the two individuals. Initially, it is recommended to text every two or three days to build rapport. However, once there is a deeper connection, texting can become more frequent. It is crucial to consider the girl's response and adjust texting frequency accordingly to ensure it is not overwhelming or too infrequent.
