Is she interested or am I being delusional?

theres this girl in one of my classes and I can't really tell if she's into me or if shes being friendly.we're doing this thing in class where we are assigned units and have to teach the rest of the students and every time she's up there teaching we make eye contact and she doesnt break her gaze but continues to stay on topic thought maybe it was because shes nervous but throughout her lessons she interacts with all the students without a problem but when we make eye contact its just this really intense gaze. when I walk into the room I can see her shift her attention from her friends to me from the corner of my eye. we have only talked a couple of times about why I don't come to class often and my reasons are mostly mental health related stuff so she offered to be someone I could come to if I ever needed to talk but shes that kind of person with everyone,always so caring.the only thing is after she said that I gave her a hug and it lasted a few seconds longer than a normal hug you'd get. her cheek was pressing against mine and I could feel how hot she was turning cause maybe she was blushing? or shes just really warm lol.I've caught her looking at me a couple of times and when I did she did this thing where she blinked really fast and looked away kinda like a twitch but then again she could have been zoning out.sometimes she says have a good day and pokes my arm until I look up at her.. does she like me or is she being nice? I've caught her blushing only a handful of times
