Missing "
Terminator 3" actor
Nick Stahl has told his wife he has checked in to rehab, TMZ has learned.
The 32-year-old actor was
reported missing earlier this week by his wife Rose -- but e-mailed friends yesterday to say he was okay and would be unreachable for the next 30 days so he could get help.
Stahl's wife, Rose, tells TMZ she spoke to the actor last night -- very briefly -- and he told her he checked into rehab. Rose says she double-checked with the rehab this morning to make sure he was still there -- and he was.
Rose tells TMZ she is not even thinking about divorce right now -- she is just glad he is safe. Rose says the couple's daughter has been asking about Nick's whereabouts lately ... and Rose is glad she can now say that daddy is safe and will be home soon.
Rose says she plans to visit Nick in rehab as much as possible, but she doesn't know how long his stay in rehab will be.

Nick Stahl has been charged with the most heinous crime in the universe -- not paying a taxi driver -- after allegedly failing to come up with enough cash to cover an $84 fare.
TMZ broke the story ...
Nick was arrested back in January when he took a long cab ride to Hollywood -- and found himself a little short on cash when it came time to pay the tab. Nick fessed up to the driver, who then flagged down a cop.
According to law enforcement sources, Nick was charged with "defrauding a taxi operator" -- and has since pled "no contest." As a result, Nick was ordered to pay a $50 fine.
But since Nick spent nearly an entire day in jail following his arrest, the judge suspended the fine. It's unclear if the cab driver ever got his money.

Nick Stahl's wife is tightening the reigns on her estranged husband -- asking a judge to limit his visitation rights with their daughter to 8 hours per week ... with proof he hasn't used drugs in the 24 hours beforehand.
Nick's wife Roseann filed the docs in L.A. County Superior Court, claiming she no longer lives with Nick as of last month -- and things must have ended badly ... because she now wants Nick limited to a mere 8 hours a week of "monitored visitation" with their daughter.
According to the docs, Roseann is willing to let Nick see their 2-year-old only while under the supervision of a professional visitation monitor ... "without Nicolas having used drugs in the past 24 hours."
Roseann is serious too -- claiming she wants "proof of a negative result for a test for drugs and alcohol within the 24 hours prior to his scheduled visitation time."
Roseann says she also wants child support because she has no job. According to Roseann, Nick raked in approximately $500,000 in the last year. A rep for Nick had no comment.
