Schwarzenegger, who had to put aside acting and his business interests while serving in Sacramento, quickly plunged back into those pursuits.
He has traveled the globe — apart from Shriver — delivering high-priced speeches and also participated in a White House summit on immigration reform. He is expected to pen his memoirs soon.
Shriver, a longtime television journalist who gave up her job at NBC when Schwarzenegger took office, has worked on her women's empowerment website, guest-edited an issue of Oprah Winfrey's magazine and promoted causes such as Alzheimer's research (her father suffered from the disease). She also took her son Patrick and some of his friends on an East Coast college tour in April.
Last Friday, after the couple's separation was made public, Shriver sent a Twitter message to her followers, which number more than 750,000: "Thank you all for the kindness, support and compassion. I am humbled by the love. Thank you."
