moving on

month 2 post break up after a 5 year relationship | this was my first ever important boyfriend so i have no idea how to cope, what's normal or the expected, how to see him living his life without me in it, how to go on with mine, how to go to places we've been together and not think about him | it's even harder because it doesn't seem as if he missed me (even tho when i've asked he says he does and that it's not like he stopped thinking about me alltogether) | im a year older so was expecting to go to his graduation party (like he did with mine), to be there for him for his last high school year trip but now im just left WONDERING and whishing i was there and i hate it | also, when do you think it's okay for people to feel moved on after such a long time together?
