Meeting up with an old HS crush this weekend

Back in HS there was this cute Asian girl that I ended in a bunch of classes with my junior and senior year. I would chat with her every now and then but I was too much of a wuss to make any sort of move on her. I had planned to asked her out to senior prom but someone else with more testicular fortitude beat me to it while I was still working up the courage to approach. Eventually we graduated and went our separate ways without her every finding out how I felt towards her.

She eventually ended moving back to NJ this year and I managed to reconnect with her. Even better, we are meeting one one one for lunch this Friday. I'm so thankful to be given a second chance but at the same time I don't want to be so overwhelmed that I end up getting super nervous and blowing it. Does anyone have any tips about go after girls in the situation I'm in? To sum it up:

1) We have past history.
2) She remembers me as a shy and nervous guy back in HS
3) We were on friendly but completely platonic and asexual terms in HS.

I framed this meet up as catching up after years of not seeing each other so that's the context of our meet up. How to I proceed from here? On the one hand, I don't to be way too "gamey" because of the context of the meet up and because I have a feeling I'm come off as weird because our past history. On the other hand, it's important to show that I am different from the guy I was back then. Any thoughts?

I think there's no two ways about this, you'll just have to ramp it up when you see her next.

This is because you have to try and get out of the 'Friends Zone' that you're in right now. One good thing I reckon is the fact that you've been separated from her for a while now. So it gives you a chance for you to present a fresh image of yourself as a viable mate to her.

I have realised that your past with a girl insofar only allows you to get into the Comfort phase with her. Ie, she won't flake on your date, she won't think you're a weirdo stranger, etc. But in terms of getting anywhere with her in a romantic sense, it won't. It's just a false sense of security, really.

As with any game target, dude, I think you'll just have to pull the trigger and crash or crash through. There are no in betweens. The risk of losing her friendship is just something you've gotta take.

Good luck man!
