Of course it is necessary, but the point is not to chat, but to chat effectively. When two people are together for a long time, their topics will become less and less, because you know each other well enough. If you are still talking for more than ten hours every day at this time, it is actually quite terrible. This means that you have nothing to do. The person who answers you for 24 hours may not really love you, but must be really idle. This kind of love has no future. How to define the chat in a relationship? I think I'll get back to you as soon as I see your news. I won't do it with you if I don't reply to other things. Whether studying or working, we should know that we all have our own things to do. Even if you don't know what to say every day, don't dig into a tricky angle to talk hard. Every day, you can find emotional buzz in the chat, so that the more you talk, the happier you will be, and then you will feel the release of pressure. If in a relationship, it is necessary to maintain a sense of security by constantly chatting, that would be too bad. Love doesn't have to stick together all the time. The most comfortable state should be that two people have their own time. We should all learn to be independent and interdependent in a relationship, and at the same time increase our trust in each other. That's a good relationship.
