Can't tell if someone wants to be friends or is romantically interested -- gee, nobody else has ever had that problem before. Must be some kind of "neurodivergent" condition that needs a made-up name.

You know that girl who was gushing over you and wanted your phone number right away but then never called? Or when you went out and kissed for ages, but then next time you saw her she wanted to be just friends? Or the one who hangs around a lot and you think "this person is into me" -- but then she says "Can I tell you something?" you get your hopes up, and she follows with "I'm having trouble with my girlfriend. I knew I could tell you because you're such a good friend."

Yeah, we don't have a medicalized name for that. People send mixed signals. They lead you on. They change their minds. Sometimes they just like the rush of you showing interest in them. Other times it's you being so hopeful that someone might be interested, so you see signals that aren't there. This is normal life for everyone.
