Is this Flirting in college?

TrevJ
I am in college and have a class with a girl my age. She laughs at stuff I say, smiles a lot at me and to stuff I say. She said hi when she saw me ask what's up. We had to do peer reviews and she came to my table sat next to me at my table I talked to her she said something, smiled at me and looked deep into my eyes and didn't stop smiling and it felt awkward, if I didn't break the eye contact she probably would've continued. One day I sat down waiting for class and she came in for class walked over and started waiting very close to me, hovering over standing in my personal space, she walked right in front of me and started getting close to me and I could smell her but she had her back to me. This was the closest she's been to me. There was a whole room not a lot of other people. When I talked about another girl flirting with me and asking for advice from some one else on how to not lead her on. She joined the conversation gave advice. said that the other girl will continue pushing boundaries and persisting if I don't say I'm not interested and rip the band-aid right off. She started this stuff after I asked for advice, afraid she knows I have issues With this now why does she seem to be Flirting. I told her someone said my hair looks like the clown from it and she said that's not nice
