求翻译：7月9日，从今天起，真的要做回那个无忧无虑的自己了。他居然没有发现，在他的列表里已经没有了那个头像，而在我的列表里，永远都只剩下那个空洞的分组，下拉菜单里永远都是空白。从今天起，他的喜怒哀乐已经和我无关，他和谁聊天已经无关紧要。我不会再去心酸，不会再去伤痛，因为那些本不属于我。是什么意思？

On July 9, starting from today, back by the carefree he really wants to do. He did not find, he was not in the list of the head, and in in my list, always leave it with the empty grouping, always in the drop-down menu is blank. Today, his emotions already and my business, who he and chat has to matter. I no longer sad, not to hurt again, because those who do not belong to me.
