Hey Hubby,

You are a saint for dealing with this. She definitely needs to see a psychiatrist for an accurate diagnosis. Making this part of an ultimatum regarding staying in the marriage is not unfair, in my opinion. If she won't go, you could look in to having her hospitalized without her consent. In the state where I live, the family member can have the person admitted "ex-parte" against their will if there is a compelling reason.

It is in everyone's, including her, best interests to get a handle on the situation, even if you have to do something drastic.
