I’m 60. I’ve been around the block more than a few times.

No, you haven’t “moved on”, you’re in here asking about her. That’s not moving on.

Let it go, find someone now, stop pining over past attractions. You’re just wasting your time.

In my experience, this sort of thing never works out the way you hope. Assuming she remembers you, she’ll be polite but confused and possibly dismissive. This is the best you’ll get. It’s not worth the effort, and it might be a blow to your ego, since you’re even considering this.

Find someone new, here, and now. Leave the past in the past. There are plenty of girls out there, go practice on them. Failure is how you learn, don’t be afraid of failing, failing is good, failing is fun, don’t take it personally, just move on to the next adventure. Yes, I said “failing is fun”, it really is if you look at it the right way. Would you only play basketball if every shot was guaranteed? Do you play games on god mode? Winning every time is boring, you know that. So, get out there and fail, and have fun doing it.
