As a couple is getting married it is very important they make an effort every day to keep their relationship growing. It is often so easy to get caught up in the business of living life, to not take the time for each other. It is so easy to grow apart.
While raising our children it is such a busy time of our life. The little people in our lives demand so much of our attention. Many times you can find yourself thinking, "Some day we will have times to ourselves!" Often, the relationship falls apart before they get to the "some day!"
The movie had a happy ending. Finally, she was able to get through to him that all was not fine. It took a bit. I am not so sure I would have stuck around as long as she did. There is often a lot of give and take ..... as it should be.
Anyway, start from the beginning make time for each other. Pay attention to what each other is saying. Address the needs and desires of your partner. This will lead to a long marriage.
