Context: already went out once. She seemed eager to set up another date asap. Then bam flaked last minute. I definitely fked up with my last msg, but I don't think that warrants a flake. She is very much a prude, which is why I waited until 2nd date. Should I call out and ask if she's nervous about something happening?
The one thing I'm confused about is why she was so invested yesterday but suddenly changes her mind in < 24hrs. First time I've encountered this type of 100 to 0 behavior in such a short amount of time.
It's one of those things you won't really know. She could be very busy, could have met someone else, could have decided she just wasn't into you. I wouldn't waste too much time ruminating over it, although I know it's disappointing. Follow up in a few weeks if you really like her. On to the NEXT girl.
