Am I the wrong here?

I was texting with my friend on Monday, and she suggested we hang out sometime. After discussing our schedules, we settled on meeting the following Saturday at her house. As the days passed, we chatted and shared memes. However, on Friday, she didn't mention my visit the next day. Being shy, I didn't want to seem pushy by asking if I could still come over. Saturday arrived, the planned day for my visit, but neither of us brought it up. I felt a bit disappointed since I usually confirm plans beforehand. It's strange because I sense she might be upset about me not showing up, even though she didn't express it directly.
