Interviews were obtained with 11 Belgian couples, in each of which one member was homosexual, in order to explore a quantitatively important but greatly obscured social problem. Many of the marriages were based on a failure of both parties at the time of marriage to define the homosexual partner as such. Admitted homosexuals married because of social pressures, as a flight from homosexuality, or on commitment to a home-centered life. Conflict tended to develop over declining sexual attention and the formation of outside relationships. Modes of adjustment that avoided separation were Platonic marriage, double-standard marriage, and innovative marriage. These adjustments were only moderately effective, being compromised by the conventionality of the respondents, whose commitment to a traditional morality yielded both marital stability and marital unhappiness.
