This is almost exactly what happened with me and a girl I knew in high school. I fell hard for her and she just wanted to be friends, and then I left for college and she realized how much she actually did have feelings for me but by then I had found someone else and we fought. I saw her two years ago and she wasn't doing too well. She cried and I tried to comfort her then I fell asleep in her dorm and we parted ways the next day. I wanted to hang out more but things just went back to being awkward. Two wars later she texted me at midnight (September 2016) and we spoke but I don't think o was what she needed. I think she wanted to open up and wanted me to open up but tbh I just wasn't ready to share everything with her after barely talking for five years. I miss her dearly and hope she's doing well, she doesn't answer my texts anymore. I'm moving out of state so I might not ever see her again, I'm debating whether or not I should just show up to her house and say hi, she still lives with her parents.
