It’s over. Why the fuck would you ever consider saying this to her - or anyone? What did you hope to gain by telling her?

“She likes classical romantic stuff but I find it kind of cringe so I don’t do them”.

Are you serious, OP? But SHE finds it special; it’s not always about you. It doesn’t have to be a big gesture or all of the time. I think it’s sad that you don’t inherently want to plan something cute to make her smile. This seems like a big opportunity to “make it up to her.” But I think anything you say or do is futile and I question how much you actually like your gf.

I forgot that you’re 36, not a teenager. Grow up.
