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

So, I met my current girlfriend in the beginning of my junior year of high school, and she was a grade level above me. We hit it off right away, hanging out all the time, but officially began dating in march of 2014. 

The following fall she went off to college in a different state to play soccer. Things were going smoothly, then all of a sudden she started to have less and less time for me, which I really struggled with. I told her I was upset and didn't know what to do. 

She recommended we didn't talk for a weekend, to see if that would make her miss me enough to realize she needed to make more time for me. So we did. Come Monday, I texted her, and she responded with we need to talk. Later that night on the phone she admitted that on Sunday, she had kissed another boy, and it was the worst decision of my life. I told her that I forgave her, and wanted to continue with this relationship, but it really crushed me. 

Fast forward a year to present day. I am now in college 800 miles away, and we are coming up on the 1 year anniversary of this happening, and it is really starting to bug me again. I found out that everybody knows it happened on the girl/boy soccer team at her university, and will still talk about it. I thought it was a secret between her and I, and finding out that everybody knows crushed me. I realized that I'm still really upset by this whole situation, and find myself crying all the time again. 

I really care for this girl, and we are even talking about getting engaged in the Summer of 2016, but I don't think it is fair for her to stay with me when I still struggle with her mistake from a year ago. 

Dear people of /r/relationships, please help me. I need some sense of direction here, or a way to get past this barrier so our relationship can flourish again. Thank you.
