Do all online friendships have a shelf life?

Freedom and anonymity online can be a double edged sword. On the one hand, makes people braver, more willing to share which makes forming beautiful and deep connections much easier. But on the other hand, people can often disappear without explanation or simply stop responding after a while. I like to tell myself that real life or other pursuits have taken up their time, rather than assuming they've gotten too bored of me :) But even if that is slightly delusion, for all the special people who have put in the effort to stay in touch and continue to chat to me, your friendship is deeply appreciated. In times like these when making new friends can be even more challenging, you are shining lights that warm the recesses of a lonely heart ❤️. So thank you again :)
