<human>: Give me a shortened version of the text

I was best friends with Katie all through high school and college. 

Two years ago, we had a falling out shortly after graduation that revolved around me doing all the work in the friendship. It was nasty and didn't end well. 

I have reached out and apologized multiple times for my behavior over the years. Katie would ignore any of my apologizes and wouldn't respond when I asked to meet up to discuss the fight in person. I thought having a discussion and heart to heart would be a good thing. 

Time passed, I moved into a large city and made new friends and started a new job. Life was good. One day I checked my Facebook and saw I had a private message from Katie which said "Hey I'm sorry I didn't forgive you, it was wrong of me. That probably seems random, but I needed to say it". 

I haven't responded as I am not sure the message is entirely sincere. In my opinion it sounds like Katie was doing it for herself, not for a sake of renewing a new friendship. 

Any suggestions on what to do? I am not sure if I should try fixing this old friendship or just be polite and distance about it.
