I am part of an ethnic dating app which I have found to be good in matching me to ppl with similar ethnicity (it is not a necessity for me to date someone of the same ethnicity but I do find that I have more in common with females of the same background so I decided to join). I found a girl who seemed really cool and we were having good conversation maybe 6-8 messages each back and forth over the course of 1.5 days. I teased her about her profile because she said poor grammar is a pet peeve and she laughed and said no i won't actually ghost someone for poor grammar. We started talking about how she just moved to my state for medical training and how its crazy hours, etc. After this period of messaging back and forth over the course of a 1.5 days or so, I then asked her to text me and gave her my number. I told her the dating app wasn't so great with its messaging functionality and therefore to text me. Instead of texting me she just deleted me as a connection so I guess she did end up ghosting me but not for grammar lol.

Did I ask for the number too quick? What happened here? I don't care too much because its just one girl but I'm kind of mystified what happened.
