What is guy only texts me every couple of days?

It is difficult to provide accurate information without additional details or context. However, if a guy is only texting someone every couple of days, it could indicate that he is not very interested or invested in the relationship. It could also suggest that he is busy with other things in his life and cannot devote much time to texting. Ultimately, the best way to understand the situation is to communicate directly and openly with the guy to understand his intentions and feelings.
