In the 1970s, the percentage of women with a high school diploma who had children outside of marriage was 13 percent. That number has more than tripled and it now rests at 44 percent. Although a lot of focus in the news is on teen mothers, a study conducted and published by the National Marriage Project says that much of the rise in the number of unwed mothers is due to partners deciding to wait to get married or forgo it completely. Many of the couples are in their 20s and 30s, in stable, adult relationships.
Everyone enters a marriage with certain expectations. For some, the expectation may be that the wife will stay home when the couple has children. Others expect that both spouses will contribute equally to the housework. When these kinds of expectations are not met, the relationship can become strained.
