30-year-old Ashley and her 58-year-old financier boyfriend were first spotted enjoying basketball games and holidays together in November 2016.
Despite the split, they have decided to remain in each others lives as friends.
"Ashley and Richard broke up," a source told Us. "She wants to focus on her clothing line right now. They're still friends and hang out."
The Full House star first went public with Sachs back in November when they packed on the PDA courtside at Madison Square Garden in New York City.
They were also spotted on a double date with Ashley’s twin sister, Mary-Kate and her husband Oliver Sarkozy as well as enjoying a romantic vacation in St. Barts in December.
