Should I ask for her back?

Hi, so me and my girlfriend broke up a few months back, we had been going strong and happy for almost a year and then I moved. I broke up with her due to intense stress and now im completely lost. I may be moving back and I am very confused about my feelings for her, so I am unsure if i should ask for her back. I always think about her and the great times we had, we always resolved our fights and she is just one of a kind. So im just unsure of what to do.
