How do I stay patient when my partner keeps postponing a big step?

I’m in a secret relationship, and we haven’t shared our first kiss yet. About three months ago, my partner said we should wait some more, and when I asked for a timeline, she said it could take years. She even mentioned that she would only tell her parents in 2-3 years, or when she moves out of her house. At first, she said she’d be ready when we’re alone on an empty street, but now it feels like we’re always waiting. How can I be patient and respectful of her boundaries while dealing with my own need for clarity?
