"They aren't together anymore," a source tells PEOPLE of the former Lipstick Jungle actress, 32, and the How I Met Your Mother actor, 35. Adds another source, "It was just time."
The pair met in 2007 when Price appeared on How I Met Your Mother, but they didn't kick off their courtship for another 18 months. "We met up a year-and-a-half later in New York," Price told PEOPLE in June. "We went to have dinner near the Bowery. It went really well."
At the time, Price said of Radnor, "He's very thoughtful, and he's very good at giving gifts."
