I would like just three points with the the body paragraphs going from the weakest point to the strongest in the third body paragraph. I am kinda stuck.

In most countries of the world, a man and a woman unite in a monogamous relationship called marriage. That relationship is made legal in a ceremony with witnesses and religious and civil recognition. This relationship is justified because one or both parties feel an emotional attachment to the other called love.
Both also feel that marriage with solidify that relationship and the emotion will bind the couple together permanently for the duration of their lives.

Interestingly, in 18th and 19th century America, well into the 20th century, some people did not often marry for love or faith-based foundations or mutual interests. They married to join good families, to produce heirs, and to have children to work on the family farm. I believe they often married fro survival, especially among the pioneers blazing trails to California, Washington State and Oregon. Certainly, some people marry for love, and some arranged, or survival marriages saw the partners come to love each other or even to fall in love. However, this may not have been the usual pattern. Survival and the drive to reproduce are extremely strong; otherwise, the human race would become extinct.

In order for a marriage relationship to succeed, there must be a foundation upon which partners build a relationship. They do this over time with experiences that add something to the foundation rather than to destroy it. These experiences should not be a temporary, superficial, or openings to relate to other relationships. A marriage foundation should include a common set of core values between the partners, or at least several shared values; or, a set of interests and passions that can join the partners together long term. Without those concepts, marriages fail to reach the goals that marriage partners thought they were striving to attain. It turns out that two major causes of divorce is a lack of foundation in the marriage, and abuse, including any of verbal, emotional, physical, economic, religious, and sexual abuses.

Divorce has some major effects on the people involved in these legal nullifications of marriage. One effect on adult children of divorce are more likely to have seriously considered suicide than their peers from intact families. Couples divorce most commonly for other reasons than not having a goood foundation. These reasons also include unfaithfulness, inability to communicate, abuse and mental illness, control, differences in personality, and differences in goals and views. More and more couples are filing for divorce in modern society. After trying to save their marriage in their own ways, some couples finally opt for divorce.Divorce also causes the divorced parties to consider cohabitation instead of legal marriage. The concept of cohabitation may encourage an increase in the divorce rate in a nation. However, if cohabitation influences the divorce rate, the states where this occurs continues to favor the marriage options over other forms of union between a man and a woman.
