My Long-Lost Childhood Crush Comes Back to Haunt Me...

So here's the deal... I've got this old childhood crush on Sarah from way back in high school. We used to be friends, and I remember always having these weird feelings whenever she was around... butterflies and stuff like that. It didn't go anywhere, though... we just sort of drifted apart after graduation. Fast forward 20 years... my wife sends me a text today saying Sarah reached out asking if there's any way for us to connect again on Facebook or something. My heart skipped a beat when I read it, and here I am sitting at my desk now, staring at the computer screen trying to decide what to do... My kids are grown and I've got this great life with my wife... but for some reason this memory of Sarah resurfacing has me feeling all these old emotions I thought were long gone. Part of me wants to reconnect just out of curiosity... to see if anything's really changed, if we can still be friends like before. But the other part of me is scared it might stir up something that never should have been there in the first place... I don't know how to feel about all this... It feels weird and wrong somehow, but also kind of exciting at the same time? So I guess my question is... am I being silly for even thinking about reaching out again after all these years? Or could there be some sort of closure or new friendship that comes from it? I don't want to hurt anyone by stirring up old feelings like this, but part of me wonders if it's better than living with the 'what ifs' forever. What do you think... Am I being unreasonable for even considering reaching out again? Or is it okay for past connections to come back into my life sometimes?
