Questions: Girl's Behavior

I was talking to a girl a few years ago. She was really interested in me and wanted a relationship. I kind of pushed her away because of things I was dealing with. It definitely seemed like a rejection from her viewpoint. I always felt awful about rejecting her, so I apologized and told her what I was thinking. I said it was my fault and she didn't do anything wrong, and that she is great. I told her it was my anxiety and depression and I didn't handle it well and I didn't want to reject her. I owned up to everything, took full blame and shared what I never was comfortable sharing with anyone. Her response was to ignore my apology and then post a picture of her all Dolled up trying to look as good as possible. Her hair done, makeup, trying to look like an Instagram model. She doesn't always post pictures like this, so the timing felt intentional. My impression of it was like a, hey, I'm great this is what you're missing type of thing.

Noone owes anyone forgiveness, but I am put off by this response. I went from feeling sad I hurt her feelings to feeling grossed out by her character. I told her she was great, and it was my anxiety and depression, and she responded like I had rejected her. I don't know, no response at all would have been one thing. But to kind of rub it in someone's face with a "Screw you im the bomb" post after someone talks about dealing with depression. That seems kind of messed up to me.

Where do you stand? Noone owes forgiveness or her response was a red flag?
