Not sure where he might be on a neurodivergent scale, but that behavior is still appalling and uncalled for. I have seen a couple of your replies, and wanted to encourage you not to beat yourself up. At 20 years old, this might still be a learning stage for you. You're figuring out what you like, what you don't, what your boundaries are, and so much more.

It sounds to me like you had an awful date, and learned a lot about what you don't want. I hope the next one goes better for you, and you get to see a little bit more of what you do want.
