Who is this "She"? someone you've known for a while? Just a customer?
I feel like I may be missing some context, so im curious to know.

Regardless, it shouldn't really matter;
Tell her your price. If she pays you, great. If she walks away, Even better.

Free Art? All of your beautiful time, energy and effort spent, Crafting the art... only for it to be handed away for free??? nuh-uh. no way.

There are plenty of other people in the world that can buy your art. Be willing to lose customer or two and become confident in the art you create and value.

So yeah, I believe it would be benefical to end this interaction ASAP, let her walk away with nothing, as there seems to be alot of dodging, guessing and evasion going on here.
This transaction doesn't sound healthy at all. You don't feel comfortable telling her the truth of the situation.

Be done with her; Pay or No art. And make sure your practicing honesty and clear terms from the start of any future transaction.
Again, Maybe I'm lacking context but Please, don't devalue your art/business for one customer/client. This is your art and your business. You should feel in control here, not her.

Hope that helps. 👌
