<human>: Can you give me the gist of the text in a nutshell?

So my ex and I broke up almost half a year ago because she was going travelling overseas for the next six months. We had been stagnating for a couple of months beforehand so we agreed breaking up was best for both of us.

In the meantime I'd been working/continuing my degree at university and I know that I've matured and changed a lot for the better during this time apart. I thought that I'd moved on, I'd been with other girls and made plenty of new friends. So it's not like I was stuck in a rut or anything. 

But now she's back in town and wants to grab coffee with me and I'm goddamn terrified. As soon as she said that (over fb) it was like all confidence just got sucked out of me and I realized how much I missed her. Not the relationship aspect, in hindsight we were just kids really, but just her in general.

Now we're having coffee tomorrow and I don't think I've ever been more nervous in my life. I'm 80% sure that she has no interest in getting back together with me, and safe to say that probably wouldn't be a good idea anyway as I plan to move overseas next year. 

I don't know what I'm looking for here, just some outside perspective maybe. Anyways, thanks for reading.
<bot>: Mutual break up for the best, thought I had moved on/was okay, ex comes back to town, and now I'm not so sure.
