I agree with all the other wise and wonderful posters! What did you confide to her? Was it extremely personal stuff? If it wasn't, perhaps just interrupting communication would seem like the BEST option here. Give it a thought, perhaps. Other than that, I am not sure what to suggest! Perhaps just try not to engage too much when she's talking to you. Just answer with a "Yes" or "No" and do not initiate the communication. Hopefully she'll get tired of this and she will leave you alone before you have to do anything? I am sorry if this is bad advice, it's the best I could come up with!
In any case, I hope things will tunr out well for you! Sending many safe, warm hugs to BOTH you, @
