Girl asked me (again) why I get nervous, and also asked me if I have a girlfriend. Is she just curious or is there more to it?

So yea, a few weeks ago this girl I have a crush on asked my why I get nervous, but at that time I didn’t know what to say so I said nothing to her, and she went away.

What happened now is that she sat next to me and asked me that question again, and just like before, I had no idea what to say, so I just said “tha what?” but she knew that I didn’t ask it because I didn’t understand her.

She then asked me “Have you never talked to girls? Why do you get nervous talking to girls? Don't you have a girlfriend?” and I just shook my head and said “No”.

I had no idea what to say after that but I wanted the convo to keep going., so I just said “I don’t go out that much” which in my language means “I’m not social”, then she replied with “So you’re introverted”.

At that point i was blushing and I could feel blood rushing to my face because she was sitting close to me. I knew I was red but thankfully she was focused on eating her food. I quickly ate mine and left.

I’m not sure if I’m overthinking this. Why does she ask me that I get nervous?
