A housewife who is pure, subservient, and devoted to her husband and family. A reference to a narrative poem called The Angel in the House by Coventry Patmore. The phrase is now typically used to question or decry this concept as a model of femininity. Though we've made great strides in the past half-decade toward full equality for women, there is still this lingering notion that a married woman, especially a mother, should be the angel in the house.
