<human>: Give me the gist of the text in a nutshell

I'll keep it short. I met an incredible girl my last month in working in another country. We got along great, both liked each other a lot, and things went fantastic until my contract came up and I had to leave. We both knew I was leaving, and decided to make the most of it. By the end I wanted to stay, but it was to late, and I thought it was just an insane idea to change my life around for someone I had really just met.

I didn't realize until I left how much I truly missed her until about a few weeks after we stopped talking regularly. It's been 8 month now and I still think about her all the time, and brood about how stupid I was to leave.

I saw her a few month ago and she seemed happy. She was seeing someone, and might still be as far as I know. When we parted I wasn't going to nsay anything, but I ended up running after her and telling her that I never should have left, and regretted it every day. She told me she wished we had more time together.

Basically, I want to know if it would be a huge mistake or not to send her a letter saying how much I miss her and moving away was the worst mistake of my life. That I want to move back, and be with her.

Would it be selfish of me to send that, or should I just keep it to myself?
<bot>: I moved away from an awesome girl.  Should I write to her saying I miss her and are willing to move back?
