He sends me text messages every night, but there is always a long time between replies. Why?

First, what does he think of you? Do you take the initiative every time you go out on a date? You should observe it first. Second, he is really busy, and some need mutual understanding, consideration and care. Third, it may be that the network delay signal is not good (but it is basically impossible). Fourth, he may not have feelings for you, but he has a good impression (does he feel contradictory). Sometimes it is. It is suggested that the landlord observe and communicate for a period of time first.
