whenever i think that this person actually understands me, they ditch me

getting ghosted by him. not even opening texts or anything but posting on instagram etc. i miss him, want to talk to him, but he's not communicating at all, although he himself had said the last time that i was important to him etc.

i sent him a sketch i made of him, im pretty sure he saw it without triggering the read receipt. no reply, nothing. why not just block me there too if he doesn't wanna talk and just avoid.
