Family life

Family is the greatest part of our life. Your spouse is the person, (You don't need a comma here.) which will be with you for ages. This is one of the most important reasons why we have to seriously consider our choice of a bride or a groom. An Engagement, a wedding, a honeymoon trip… (Just put a comma between these and use a lowercase a) All this these entertaining things are just the first step of a difficult way. Lovers and even newly-weds (It is just one word, no hyphen.) rarely think about it. However, this way has its charms. The greatest part of family life is our children. It is real happiness to expect a baby, anticipating washing the newborn’s nappies, and to passing away sleepless nights… (Use a period instead of an ellipses.) It is amusing, (You don't need a comma here.) when your relatives notice resemblances between your child and you. You feel a real pride when the teacher tells you that your child does well in school. Moreover, family holidays, traditions and other common events are really amazing. They help to realize that you are not alone. However, it is difficult to preserve the union with your husband or wife. At least it is necessary in order not (Use "It is not necessary" if that is what I think you are going for.) to join the ranks of one-parent families. These days, an increase in divorce rates is a global problem. It means that we must treat the marriage more seriously. We have to think twice before make making this important decision, in order not to to not spoil our family life.

Good job overall. =) You were just mainly missing articles and a few unnecessary or missing punctuation marks.
