Why do some people never reply to text messages?

1. This may be related to the other person's personality. The other person is an independent and competitive person, and he may think it doesn't matter if he can't reply to the text messages. As long as he confirms that he has seen it, he cares more about his feelings than others.

Maybe I just don't know each other well and don't think it's necessary to reply to each other. For example, the relationship between customers, many customers do not like to reply to text messages.

Maybe I'm not interested in your words at all, or maybe I just don't want to be friends anymore. I think as long as you don't reply, you may not contact him again.

We know each other too well, we don't feel the need to reply, and it won't affect your feelings, and they all know you well, so you won't care if you don't reply.
