I'm approaching this from a Mythic Tarot perspective. In that deck, the 8 of Cups embodies Psyche, who is tasked with seemingly impossible challenges to prove her love to Eros. The final challenge is to enter the underworld, and she accepts this knowing she won't return. She lets go of preconceived notions, entering with full commitment, acknowledging that she's given her all. There's a sense of despair, but she doesn't look back. This is the foundational perspective from which I provided my answer.
There's a profound transformation occurring. The person is taking it to a deeper level voluntarily, surrendering the dream without waiting for the outcome. It's an abandonment of the old way, accompanied by tears.
All 8s symbolize death and rebirth—a transformation.
In the Victorian Romantic Tarot, the woman is depicted walking away with a sense of sadness. I haven't perceived it as moving towards something new with excitement, but more as leaving something with a sense of sorrow. However, with every ending, there's a new beginning. So, you can say that by walking away, she is also moving towards something.
Indeed, it could signify asking someone to marry them, but in the sense of laying it all out on the table without waiting for a specific outcome. It's more about the person expressing their feelings rather than the recipient.
Maybe I didn't articulate it clearly before, but this is how I interpret the 8 of Cups. 💖
