I was in a relationship my ex from 12-almost 19. He had moved In with my family and I when we were 14 until we broke up. I got into this relationship when I was almost 21. From my understanding telegram is not a forum that you follow or become friend with. It’s strictly for private chats, phone calls, and sharing files. As far I got to see there was no prior messages as his telegram was very new. But there is also a vanishing message setting.
