The narrative is that after their 10 year tryst she "went mad" and was committed to an institute where she died, which might sound like a familiar historical narrative to you, especially about talented women during this time period.
Articles like this wash women in history out of the conversation and are gross. They find the bits of history they want to celebrate and ignore the harder truths that led to a fascinating (but tragic) creative process.
