Hello, my friends

I went out with a girl but she seemed to be absent (physically she was there, but…).
I was always talking about lots of different subjects just to see if she contributes to the conversation but I came to the point of shutting up for sometimes just to see where this was going. It didn't improve much!
In two occasions, we were in my car, I asked her a question but she didn’t even replied, i.e., she wasn’t even listening what I said.

We have a week of “friendship”, jogging together and a coffee every now and then. But now she seems to have lost her interest.

How do you deal with a girl like this? Input is appreciated.

Thanks
