To "confront" someone means to speak directly to them about a problem, a complaint, or a criticism. In the example above, "confronting" the husband would mean asking him something like:
Why have you been coming home so late every night?
Are you cheating on me?
You always have to have an object for "confronted". That means that you always have to say who got confronted:
Did she confront you?
To tell what the topic of the confrontation is, use "about ___".
