One day after telling his friends via email that he planed to seek treatment, Nick Stahl entered rehab, his wife, Rose, confirms to E! News.

The actor, 32, was reported missing Monday. Rose had last seen her husband May 9, and she'd perviously filed court papers expressing concern about the actor's suspected drug use.

"He wants to be well," Rose tells E! News. "He's a good man and we want him home so we can help him."

Rose adds that her husband was "really working hard" at his sobriety at the time of his disappearance.

Stahl is best known for his role as John Connor in 2003's Terminator 3: Rise of the Machines.
