Just had a roommate the other day turn down a guy for ice cream date (she was pissed atm) and then began worrying why he hasn't ask her out again, despite other (smaller) rejections in the past. Anyone would expect these people to be relatively young, but nah both of them in early 40s. Not everything is logical. Yesterday they went on a date.
This could be one of three things.
First one (and you're right on the money), is emotional cresting. Prehaps you did something which made them so emotional, that by the time you get back to them, they no longer feel it. I don't believe it's having to act at the moment (which of course, it should totally be done when possible), but more that they feel cheated or betrayed by their emotions and auto-reject. "Why was I so happy to meet Lux? That's to good to be true." A mundane explanation is that you simply elevated them to an emotional high, who knows how they normally feel?
Second reason, which I've seen guys do often, is fear of fucking-up (which is arguably an auto-rejection in itself). Like so many other unanswered texts, they receive it and go "Shit, I can't/won't answer this now, I'll do it later." Later never comes, because then they forget about it and either feel so shitty/embarrassed they won't answer regardless, or they'll go "If I forgot about it, I'm actually not too eager to met this guy at all. It's for the best." Instead of actually not being/not bothering to text, they get frustrated about not losing their chance with Lux that they decide they actually "can't" text right now and either scenario comes up.
The third reason, hugging you in a dating/day game context is her way (conscious or not) of telling you that you could have escalated the interaction, and that at least she'll get some affection out of it. Related to emotional highs, but a separate concept. If it's not socially expected and it isn't one of her habits, then going from | no-hugging ----> hugging | is her way of escalating your interaction; marginally so on one end of the spectrum (Latin communities) to hugely on another (conservative Muslim communities).
Take my advice with a grain and a half of salt, since I come from limited experience (I can count exactly how many times this has happened to me in similar situations). Also curious to know what other members think about this.
Just text her again or find some way to meet up with her. The only thing you'll lose is a bit if pride if she doesn't answer back (again), but you could get laid. I'd try to be more aggressive, so to speak, the next time this happens and/or be more attainable. Lower attainability would lower the pressure she has in meeting you, while it's obvious to say that aggressiveness is you escalating things further to up her commitment to you or reward/match her emotional state (which is a form of investment in you).
