I recently went back to college at 28, meet a girl i think 19-20, that sit next to me. Light conversation at first "hi, I'm OP", "Hello I'm she". talked more here and there but never really more then 10 minutes and nothing really but about class again because we one have 10 minutes before next classes start, but i noticed that she just about always blushes when i speak to her and laughs at anything after everything I said heck I once said that i wasn't feeling and was going to skip my next class, and she thought it was that funniest thing ever. So, I asked if she wanted to players checkers (made a joke last class because she was drawing a checkered board), she said she didn't know how to play, offered to show her replied

"I can't i have class" which i probably true bc i have on also

so, today class was cut short today by probably 20 minutes because it was a test day, started talking to her after class, asked if she wanted to sit, her reply

"I'm busy and have to go". said ok and went to leave but not before she said "i'll see you next class"

I just don;t get it, i think she's giving me all the body quote, blushing, fixes her hair when she first see me, laughs at everything i say. But doesn't want to hangout. Honestly normally at this point i move on if it wasn't for again the quote. should I just call it quits?

Side not: both times i asked her to hangout was probably a week apart if that relevant, also after the first time she started to seem more interested, idk my people of reddit, Thoughts?
