Okay Rob,
Usually this is pretty binary (0/1), but I can remember this one incident from quite some time ago on which I can still not put my finger. Girl gave me an obvious approach invitation which I used promptly, I deep dived well, had a good connection. I asked her out and she agreed very enthousiastically. I finished conversation and went about my business and not 2 minutes later she started verbally resisting me hard publicly, pretty much backpedalling after our conversation was already over. I was in no position to persist, so wrote her up as a lost cause. 10 minutes later I noticed her staring at me with a confused look and I was really creeped out because of the weirdness. She was a really nice girl but the behavior was all over the place and I had to think of my reputation. (Social circle)
Next time I saw her, she was VERY happy to see me (weird huh?), but I already had moved on, I guess I had autorejected myself, which in some cases is a healthy thing to do. Soon after I met some new girls, which she noticed and flew into autorejection pretty bad. Afterwards I noticed her going out of her way hovering around my workplace (she is not a colleague, but I noticed her across the street where she had no business) while also being really tense.
I get attention seekers, I also get compliant girls. But these flip flopping types, what do you make of them?
