Detach GG, so it doesn't really matter how he reacts. It will be more about YOU being the bigger, more mature one. And doing the 180 or LL or whatever it is you decide to do.
I would actually expect it to go "just OK". Sitting here, detached from your sitch, like it is a movie, I'm already seeing what will happen--you meet, you give your script (or gift), a bit of chit chat about nothing, but you'll be looking him in the eye (respect), not mad (he'll feel it--and it's a 180). If it goes a little further, great, if not, it was still good. A little light flirting would be AWESOME if you could manage it
If H gets mad, which, I rather doubt it (I think he'll be too surprised) you validate and wish him a good day and it's still good.
And you will come back and these guys will tell you you did the right thing, gave H something to think about, and you may or may not be encouraged, but you SHOULD be, because in the end you ARE the bigger person.
