How long does it hurt for?

We were dating for 2 years and now It’s been a month. No contact. it still feels like a crater has been left. And it’s not like it was even out of the blue. I’d been asking for answers for so long and it felt like I was just being strung along. Then when he brings it up himself… well.. let’s just say it hurts a lot still. And I made the mistake of looking at his social tonight but he looks so okay. Am I the only one hurting? When will it feel like I’m finally move on?
