update: he left and stopped talking to me

16F and i posted here before. he left the country and now he’s basically ghosting me. at first it was “busy” and time difference but now he just doesn’t reply or leaves me on read. before he left he kept saying nothing would change and we’d still talk. now i just feel dumb for believing that. i keep checking my phone even though i know he probably won’t answer. idk what i did wrong or if this is just how things end sometimes. how do you get over someone when they don’t even explain?
