So let me save you some time. If someone leaves without a word, don’t chase them. Allow people who want to leave like that to leave, even if it breaks your heart more than you could ever explain. The hardest thing to realize is that not every friendship is meant to last forever, as much as we wish it would. So many friendships are meant to show us things, good and bad, about what we want, what we need, and who we do and don’t want to be, and who we do and don’t want to be around.
