Did it
Despite the "Story update on the 20-year-old," we did get together late last night, which caused suffering today but was worth it. I've also remembered something I discovered a long time ago: the greater the logistical hassles, the more my interest declines in the girl. The older I get, the greater this effect.
Sometimes, however, this can have a paradoxical effect. I lose interest, and the girl gets more interested because she senses my uninterest. More often, I lose interest and so does she. That's probably why I have so many long and pretty cold leads, and why sudden re-ignitions or techniques like this can work.
Speaking of the 20-year-old, there will likely be one or two days of overlap between her getting back and me leaving. No idea whether that will work. I'm still into her, but flakey or just logistically complicated girls turn me off over time.
I'm beat, but there are probably a handful of you curious about the (mostly surprise) outcome. I also have two pretty good pieces coming along, based on replies to comments.
Still not sure I'm actually going to see this one again.
