I'd say grey rock and avoid as much as possible. Hopefully if she's your husband's sister, he sees her behavior for what it is and gets good about setting boundaries. If she's your brother's wife, good luck. It'll likely eventually explode, but he'll endure years of abuse and hurt others in the process before he snaps out of it.
This. Although it may not be mental illness. Or it may not be JUST mental illness.
She may have a personality disorder which almost definitely means that the only solution is to avoid her.
