Answer:
substantiates the "U-shaped" pattern, where marital satisfaction is high at the beginning, drops down around the birth of children, and then gradually rises back to its original high level.
Step-by-step explanation:
The feeling of excitement of the unknown is what contribute to the high satisfaction in the beginning of marriage. But overtime, couples become used to each other and that feeling start to become dull.
Before the birth of children, couples tend to have a lot of time to spend to pay attention to each others.
After children are born, taking care of the children will take a huge chunk of time that the partners have in their life. When this happen, time that they spend to actually communicate and courting each other will start to gradually decrease. If this left unhanded, marital satisfaction will start to gradually go down. But, if it's properly taken care of, the partners will find a more meaningful reasons for their relationships and the satisfaction will gradually rises back.
