When I Tried to Win Back My Childhood Friend's Heart as an Adult

So here’s the deal. When I was a kid, I had this friend, let’s call her Sarah. We were inseparable in those summer camp days when we would play hide-and-seek behind the big pine trees and never get caught by counselors looking for us. But after high school, she moved away to another state. We kept up through letters for a while but eventually lost touch as life took over our paths separately. Fast forward to last year: I was at a class reunion where Sarah happened to be attending too. It had been so long since we saw each other; there was an instant spark again, like old times. But this time, it wasn’t just about friendship, it felt deeper, something more mature and grown-up now that decades have passed. I thought, 'Why not?' Why shouldn’t a middle-aged person experience that same fluttery feeling of first love? I started reaching out more often, sending texts about our favorite memories from childhood. I even suggested we meet up at some local spots to catch up on old times. The problem is, Sarah seems to just see me as her friendly old buddy from way back when. I’ve been stuck here for months now, wanting something that’s clearly not there. It feels so silly but also really frustrating because I can’t shake the feeling of wanting her to notice a change in our dynamic too. But every time she acts like nothing has changed, it just reminds me how much of an oddball this whole situation is. Am I wrong for wanting more? Is it normal to hope that after all these years, someone from your past can be something special again? Or am I the asshole for thinking any of this was possible?
