TLDR: I fucked up and gave validation. Can I humble this girl or do I take the loss?

Ignored a girl for two months after telling her that I wasn't chasing her. Meanwhile, I was with other plates and thought about her. I fucked up and offered to hangout. She ignores me then posts on social media that she declined "a paid-for meal". I shouldn't care but wish I could take that back and humble her. Any advice?
