misogamy

If you know a confirmed bachelor who dates a lot but never settles down, he may not have met the right person yet — or he may suffer from misogamy, a hatred of marriage.

Misogamy is made up of two Greek words, mis meaning "hate," and gamy meaning "marriage." You might get it confused with another mis- word that sounds similar, misogyny, which is completely different as it means "a hatred of women."
