Met this cute college chick on the plane. Throughout the trip, there was noticeable tension between us, lip-licking, hard eye contact, knees brushing each other, etc. So we exchanged numbers.

Texted her two days later to which she responded instantly. İ suggested we go do something to which she replies "if I'm done with my homework I don't see why not" lol and that she was really looking forward to it.

The day of the date, I ended up cancelling due to some other important shit. I tell her something like get all of your homework done because I'll be back (we live in different cities) next weekend.

And she responds with just ":P", when before, she had been sending multiple sentences

Now I'm pretty sure I'm on the spectrum lol, but my gut instinct is that either this is somehow flirting or that I said something awkward and fucked up the vibe/she's no longer interested/she was never that interested in the first place.

What do you guys think?
