<human>: Can you condense the text into a few key points?

I had been dating this girl for over a year. She seriously was the best thing that ever happened to me. However, we had a few problems towards the end. Basically, I was moved for work to London briefly, and this brief period went into a few months. During this time, I was supposed to go and visit her, and her family. I delayed unnecessarily and she was patient, up to a point. The suddenly, I had to go to Paris and that was the last straw. She broke up with me. I did not take it well and effectively blamed her when it was my fault. Things have not been good since, however we have exchanged some texts and emails. I feel like if I get her to see me, I can get her back. I miss her dearly and she means the world to me. I was a fucking idiot and screwed it up. I am in town, where she lives, and I sent her an email basically "to hang out and see what happens". I feel like she will come, she's that amazing. How can I play it to get her back? I wanna casually see her as friends before I say I want her back. There has been some drama and unfortunate incidents but we both said some shit we regret. 

Reddit, I want her back and I need some advice on how to do it.
