"Spouse" is kind of loosely defined.
I wouldn't define someone living with another woman and two kids by her as a "spouse," but I'm old-fashioned.
But legally, I suppose you're right.
No, you're not out of line. But I wouldn't have done what Michael did in a million years so there's no real identification with his situation for me.
Although it's obviously apples and oranges to a large extent, I can't help but think about what role the husband would be given in our current culture in deciding something for his helpless kin if his wife wanted an abortion without his consent.
By any definition we have been working with, a fetus is far more alive, aware, and with the potential for full humanity, than Terri is.
