Smartcookie has some very good questions. Do you need to protect yourself financially, of course, but also don't do anything too drastic that might push her into battle mode.

Are you and W able to discuss things like this rationally or will she feel like you are checking up on her?

FWIW, if you feel like you might be in a bad spot, then go with your gut and see what you need to do to protect you. If you have to make the moves then do so, but I would get more information first. Just my humble opinion.
