Who is Ruth's husband?

Teddy, Ruth's husband, is an expatriate to America, where he lives with his family of three sons, just like that of his father, and works as a professor of philosophy at a university. He claims to love his family but also expresses some ambivalence towards them. He was however, Jessie’s favorite son, according to Sam. Teddy is a logical, practical, generally emotionless figure who does little to intervene in his wife’s behavior with his brother. He only half-grudgingly leaves her to return to America, a place he loves for its cleanliness and the orderliness of his university life.
