<human>: I met this girl close to 10 years ago. We both have confessed having feelings for one another, but never at the same time. I should mention theres a lot of other complicated stuff too but I don't feel its worth going into detail about.

I'm not really interested in persuing a relationship with her, but this has really been bothering me since the last time we spent time 
together 5 years ago. She's the first girl I ever had serious feelings for and I feel like I keep reliving this same experience with other girls.

Heres where it gets complicated. I found her on social media like 3 years ago and told her for the first time that I had feelings for her. It felt fantastic to let that out, but she was kind of cold toward me or possibly wierded out. 

Again, telling her how I felt was like having 1000 pounds lifted off my shoulders but I feel like to get full closure I need to know her side of the story. I also feel like it will help me in future relationships.

Is it wierd for me to track her down a 2nd time and ask her?

Can you condense the text into a few key points?
<bot>: Looking for a "Post Mortem" (Ever see that episode of "The Office" where Michael goes to all of his ex's and talks to them about why their relationships ended?) via social media a 2nd time.
