It is not accurate enough to judge whether the other person is just chatting with himself by the speed of chatting. If this person can't fully concentrate when chatting with you, even if you don't know what you said, just simply "uh-huh" to deal with you, it must be chatting with many people, because he won't notice what you said at all, but will only answer mechanically, which will easily expose him.

It's hard for normal people to multitask and concentrate on one thing. If the other person's chat reply takes a long time and has been processed, it is not a special chat with you. Another way to judge is that she doesn't send you text chats, but sends a lot of expression packs, which seems to be dealing with you. The fastest way to chat is to print words, which is very simple, without typing, and of course boring. At this time, you should pay attention.

The other person probably doesn't want to continue chatting with you, they are just dealing with your chat. Finally, there is a way to judge whether the other person is chatting with you specifically, that is, you will receive a sentence from him and take it back quickly. If it is once, it may be that he didn't edit the text well, but if it appears many times, you should pay attention to it, indicating that he is chatting with others. He probably sent you what he wrote to others, which is why he withdrew it quickly.

After all, chatting with many people, he may wonder who it is sent to. There are many people chatting, and they have to reply quickly, so the quality of writing is definitely not good, so there are often many loopholes.
