Was she coming on to me?

I’ve kinda I guess flirted / teased this girl in the past. I flirt by teasing and I thought it was fun with her and it seemed to work lol. She was inches taller than me and i would make height jokes and then she would reciprocate about how I was tiny or something or the same size as a stuffed animal and we’d laugh and she’s touched my arm while laughing.
Once we were kinda alone and I noticed she kept lingering around ( this was at work by the way ) and I told her her singing was awful and she should shut up and she kinda gasped and laughed and said she was gonna come over to my place late at night and sing me to sleep. I then was like “oh my gosh” because I got flustered and then she laughed.
She is secretly a sexual person lol I’ve seen her social media and she’ll make dirty jokes on there so could this have been sexual?
