I work as a tutor for university students, and I have a student who seems to be flirting with me but I'm not sure. Under most circumstances I wouldn't be in any doubt about it, but she's been diagnosed as mildly on the autistic spectrum and, after having worked with a few students with a similar diagnosis, I've noticed that they can be very open and unguarded in a way that could be misinterpreted.
When we meet for tutorials we might, as I think is normal, have a bit of small talk at the beginning, but she gives me lots of quite personal info about what shes's been doing e.g. she talks a lot about her pole dancing classes and sometimes mentions outfits she has bought. However, she does talk about it in a very matter of fact way . She has also emailed me photos a few time, but nothing sexual, just a new haircut, new nails etc
I have a partner, and I have considered no longer having tutorials with her, but she's quite a sensitive person and might take it badly, and it is entirely possible that she is just being very open and friendly and not even realising that it is coming across differently.
