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

I have been dating this awesome girl for 4 years now and for about a year now I have known that she is not "the one". 

I graduated in May and am living away from here working full time. She will be graduating this coming may and will most likely not end up near me. The distance doesn't bother me at all, its more of the fact that she is not the girl I want to end up with. I have no idea how to tell her this because I see her so seldom and I haven't really ever broken up with somebody before. 

I still lover her but not to the point of marriage. How can I bring up this topic and have a discussion about it without ending the relation ship on bad terms.
