Legal Question in Family Law in Washington

I am not sure to whom she refers when she wonders whether to report him. That said, spouses do have a general fiduciary duty to each other to take care of each other. If the wife feels her husband's health is literally in danger and that he is starving himself, she may be able to have him committed and treated on the basis that he is mentally incompetent, if she can show that he is not aware of what he is doing to himself.

On the other hand, if she really wants nothing to do with him, she can leave him, and let him fend for himself. I've never heard of anyone being prosecuted because they left a spouse who drank themselves to death. There is no doubt how said this would be, but it is common.
