Thank you for sharing, I hope you’re better now

Yes it is on a dating app.

Talking for hours and hours on end while sharing a lot of the same interests and talking about it vividly. Discovering you’re totally sexually compatible while being a minority so not a lot of occasions in the dating pool. Agreeing to meet each other for coffee or to see a movie, then ghosted? I don’t think I am misreading signs for this specific person here.

Just cracking a joke and having a little conversation without nothing much, I wouldn’t call it ghosting.
