I can't get "unstuck"

I'm sorry you're feeling that pain and torment. I've been there. It sux. I spent countless hours talking out loud to no one while driving or in the shower or wherever, just to try releasing some of that inner turmoil. As many others pointed out on these forums, it's part of the addiction. 

When I was in my early 20's I was dating a girl for 5 years. She was a DA although I didn't know it then. We had the textbook push-pull relationship. I asked her to marry me and then she broke up for good within a few days. It took me 2 years to finally get over her. I wish I knew about attachment types back then so instead of blaming myself and wondering what I did wrong, I could have possibly understood what the real deal was. 

Try to not visit her social media page. It only brings pain. Trust me, I know from experience. 

When things ended for you, did you get closure or was it a total surprise?

Looking at this from the outside, I get the feeling that the need for her reaching out to you is caused by a lack of personal validation. It seems to me you're looking outside of yourself to 'fix' something that's inside of you. In my experience, that doesn't work all that well. To get unstuck, as you call it, I think your attention needs to be transferred there.

I read this every day since I broke up with my ex FA, and sometimes twice or three times. Yes, you left the relationship but you're still very much tied up in it. I hope this information is as much of a revelation as it was for me.
