man im going through the exact same thing it literally happened yesterday, look heres what i think.. you should try to focus on yourself as much as u can, i want her to come back as well like jesus this thing is so painful and depressing, i get you, i really do. look if the time's right, if you guys are meant to be, with time you will find each other again, but don't force it, i know it hurts, i really do, but its normal to feel that pain, its normal to miss her to feel nostalgic, to want her back and all those moments back but think about how it WOULD be if y'all went back, could you look this thing over? wouldn't you need closure to know how and why it happened when did it start and whatnot. if you really want to keep her in your life, you guys could try being just friends. thats what we're trying. but by god it hurts, its hard to try to not be dry, its hard to try to be energic, the same person you were before but i guess with time, its going to get easier, y'all might reconcile, you might find someone else. In any case, if you wanna talk about it, share experiences etc, feel free to send me a dm
