Disappearing after making plans with someone is not a polite or cool thing to do and so the girl is not someone who is worth being elated about.
Context: Me and this girl on Tinder were going really steady, then out of the blue she flat out ghosted me.
Hypothesis: After being so excited to go out with this girl I met on Tinder, I was elated when she suddenly disappeared

Is the hypothesis incorrect? (Yes, no, or unknown)?
