As the former wife of McDreamy, Addison Montgomery is maybe the most famous divorcee on national television.
But Kate Walsh
, the woman who plays her on both Grey's Anatomy
and its spin-off Private Practice
, never imagined that she would have to go through the same ordeal off-screen.
"I don't think anyone gets married thinking that they will get divorced," says Walsh, 41, opening up about her divorce from film studio executive Alex Young, 38, for the first time in next month's Redbook cover story
Walsh adds: "Alex and I still care for each other, and I wish him nothing but the best."
And the actress gave praise to the people who stepped up to comfort and support her during the difficult time.
"The silver lining to this, however, is that I have a wonderful family and a great group of friends who really showed their support and encouragement, and for that I am truly grateful," she says.
In December, Young filed for divorce
after 15 months of marriage citing irreconcilable differences. The couple had tied the knot last September after a three-month courtship.
"I second-guess myself all the time," Walsh told the magazine. "I make a decision and then wonder if I made the wrong choice. Sometimes I come off as confident, but really I am a quivering little wharf rat underneath."
Right now she is a wharf rat in need of a date. Walsh admitted to Redbook
that her favorite form of courtship – calling a guy and then hanging up when he picks up – has been made obsolete in the age of caller ID.
"Remember when you could mildly stalk a guy?" mused Walsh. "Not anymore, man. They can be at your front door in five minutes. There's just no mystery now."
