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?

Or even:

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 ___".
