What kind of experience is it that friends who have been together for a long time suddenly don't contact?

But from my personal point of view, if my friend suddenly stops contacting me, my first feeling must be that I am worried about my friend's health or my family. I will definitely call frequently and ask about his recent situation through other friends.

If it turns out that there is no trouble in his life or even if something big happens, it will not affect his communication with his friends, then I can only admit that he did break up with me unilaterally while putting down my concerns.

When I realize this, I will feel very uncomfortable, because I don't know what I did wrong, so I suddenly refused to go to the current account. I will slowly recall and review whether I did something wrong unintentionally. Inadvertently saying the wrong thing makes a friend sad and makes her make such a decision. If you find nothing after summing up.

Then sadness and discomfort will turn into anger. Why? Why not say no contact? This simply doesn't take me seriously.

Since you don't take me as a friend and I don't need to miss you, let's be strangers from now on. But you will regret it, because losing me is your loss. Of course, this may just be to comfort yourself and make yourself comfortable.
