They dont text for weeks and when they do text they dont bring anything to the convorsation. And when we talk about something they change the topic when its my turn to reply. And dont get me started when they take 41 minutes to reply to each text :[ I know people need time to reply but when you only need time when I wanna talk it is a problem.
You have to "read" those people in their behaviour. Its classical ghosting, which I think is one of the worst sides of a charakter.
On the other side think about your own way to conversate: Not everyone have to like the topics you might want to talk about. And not everybody wants to say: "Not my topic, sorry. Next one please!"
Just need some experience. And you can always
calculate that a few of a dozen conversations are only just a few Messages or sentences.
