Cap guy, Asked a Virgo girl out but she declined, Do I still have a chance?

Hi!

I've met a virgo gal and been seeing here at my Uni for the past few days, at first she was kinda quiet around me but always sat down next to me, and we spoke every now and then.

One day I just asked her out of the blue "So, are you this serious all the time or just when you're here?"

and she immediately replied "Yeah I'm kinda quiet. Do you think I'm too quiet tho?"

She seemed unsure of herself when I asked her that, almost as if she were being judged or something. I was amused and just laughed a bit!

"Nah, it's fine!" I said.

"Once you get to know me, I'm not so quiet!" She said.

After that day, she became noticeably more chatty with me and more open about things. Like if I somehow gained her trust when I asked her why she was so quiet lol.

So, this last weekend I sent her a message and asked her if she wanted to grab some coffee with me. She said she had plans with her family that day.

"Oh okay! Have a nice day 🙂" I texted, and she just texted me back "Thanks! See you tomorrow!"

So today (Monday) we arrived at Uni, I was studying and she just came in and kissed me good morning.

(On the cheek guys, on the cheek... the one on my face!), something she rarely does.

I'm a bit aloof and and I don't pay much attention to anyone when I'm working/studying, as I'm a bit

obsessive with my studies so I didn't talk to her for the rest of the day.

I saw her last when I was going home (Had a family reunion today and needed to arrive early), she

again said hi to me and wanted me to sit next to her to talk but I told her I needed to go because family.

I think I probably appeared a bit rude today towards her and I'm a bit worried she might get the wrong message.

What would a virgo girl/woman think if she were in this situation? Did I do wrong today?

Any help appreciated 🙂
