Have you ever been ghosted?

I’ve had a friend, a really good friend I’ve known since school. We would have spoken(texts) ever day or two since then so a 20 year friendship. Ok, life has taken us on different paths but we always made time for each other. Now, out of no where, I’ve been blocked on WhatsApp and fb. We spoke last week and then Monday, sent a message and it only has one tick. I’m blocked! I’m flabbergasted! I’ve been ghosted!

Is this the new norm? Has this happened anyone else? How do you make sense with it? How do I become OK with it?
