My teen is in romantic crisis and I have no script

They like someone. That person is 'busy.' My teen can't read the actual situation (are they interested? uninterested? slow-burn? over?). Anxiety is eating them alive and I have no framework to help.

Romance and ADHD/autism = recipe for misreading + heartbreak.

How do you help your teen navigate dating and crushes when they misread social cues?
