[26] McClory, Turning Point, 88-94, 102-106. The Crowleys had gathered replies from three thousand members of the Christian Family Movement living in eighteen countries. 43% of the couples using NFP said they found it helpful in spacing their children. On the other hand, 78% "claimed that it had also harmed their relationship due to tension, loss of spontaneity, fear of pregnancy, etc." (90). As an example, a wife of fourteen years with seven children writes: The slightest upset, mental or physical, appears to change the cycle and thereby renders this method of family planning useless. Our marriage problem is not financialů But my husband has a terrible weakness when it comes to self-control in sex and unless his demands are met in every way when he feels this way, he is a very dangerous man to me and my daughters. Apart from these times he is completely normal and tries in every way he knows, such as morning Mass, sacraments, prayers, etc., to accumulate grace" (91).
