<human>: Can you give me a shortened version of the text?

Hi all,

My gf (F 26) of almost 4 years just broke up with me (M 25). So the story is, we moved in together about two years ago. I was very unsatisfied with my old job so I asked her if she would move to me to middle of nowhere if I could find a better one. She said yes, find a job first. I applied and got an interview so things where moving forward at that point. Progressively, I scored the job and she encouraged me to take it. The company flew us out here to scout for apartments and I brought her to show her the area. Eventually I moved out of our apartment to another state few months ago for the new job. 

At first we talked every night and facetimed. After just two weeks at the new job I was able to already fly home for the holidays for two weeks. She was a bit more reserved when she picked me up at the airport and things were weird but it eventually got back to normal. The vacation was short lived but it was well spent. I flew back to my new state and we were still in contact frequently but this past week or so she stopped returning my text and phone calls. 

I confronted her today and she told me we should break up.  She told me she has lost some feelings for me and she doesn't miss me as much as she thinks she should. 

I also want to mention that she did try to look for jobs here but she didn't get any replies back so she lost motivation; meanwhile, her current job got new management and she started picking up more responsibilities in a good way. Now she is unwilling to move here with me leaving me here stranded. She admits that she screwed me over. 

Reddit, what should I do? I was so set on marrying her. I guess I should've put a ring on it.
