Even though i told my ex to block my number, I kept texting my ex for some emotional release knowing that he blocked me and that he wont receive my messages. At first, my messages didn't show as delivered. But my friend made me suspicious so to check, I sent a voice message, and it seemed like he heard it as it disappeared after 2 minutes. Strangely, later i sent two other messages which also didn’t show delivered. But about 30 mins later i checked and it is suddenly saying "delivered". It's confusing, and I'm not sure what's happening. Most of the stuff i sent aren’t appropriate, and it is driving me nuts.
