Why can't I get over her? I literally moved 500 miles away

I don't know. I don't have an answer for you but I know that feeling. An older coworker confided in me that she had the same problem. A man she was going to marry broke up with her after treating her pretty poorly for a long while. Their relationship wasn't going well and he wasn't willing to fully commit to her. She's "moved on" and dated since then, but not a day goes by that she doesn't miss him. She said she's not sure if you ever move on, only that you some day learn to live with it.

I'm beginning to think she might be right. I'm not sure if every relationship is one we move on from.

Man the fuck up dude. I just got broken up with 2 weeks ago, and there's only a void because you don't want to move on. Think back to when you were in high school or whenever you didn't know her. Was there a void in your life then? Or did you just get too comfortable and used to this girl that not having her creates a void in your life? Get over her man, life's to short to not enjoy it

read up on "co-dependency". you have issues (likely low levels of differentiation of your self) that make you attach and depend way too much of your wellbeing to and on HER.
