Westheimer has been married three times. She said that each of her marriages played an important role in her relationship advice, but after two divorces, it was her third marriage, to Manfred Westheimer, that was the "real marriage." This lasted until his death in 1997. She has two children, Miriam and Joel, and four grandchildren. In December 2014, Westheimer was a guest at an Orthodox Jewish wedding in the Bronx, NY. The groom, Rabbi Benjamin Goldschmidt, is the great-grandson of the woman who had helped rescue Westheimer from Nazi Germany. She still lives in the "cluttered three-bedroom apartment in Washington Heights where she raised her two children and became famous, in that order." Because of the two synagogues she belongs to, the YMHA she was President of for three years, and a "still sizable community of German Jewish World War II refugees", she remains in the neighborhood. She speaks English, German, French, and Hebrew.
