Stay off the internet in your dealings with her, 42. Your friendship has cooled off to the point where it'll probably be as awkward as just before she went back to japan. You're going to have to start from square 1. The next time you see her in person and your eyes meet, force yourself to smile and not look away. Say hello. If she responds positively, make some chit chat, keep it strictly casual and keep it short. If not, let it go.
