Why did it upset her?

So there is this girl, she said it was better for me if i didn’t get into a relationship with her because she wasn’t fully ready.

I still see her sometimes as we have some of the same friends and everytime the energy is just the same. We were shopping with some friends yesterday and an older man that worked at the store told us we were a nice couple.

I noticed she got a little awkward because of it, so I told the guy thanks but we aren’t. And that upset her and she went straight home and hasn’t talked to me since.

Why did that piss her off? Or upset her
