One of them is that they are madly in love and love moves mountains. Some of the other reasons are that they are pregnant, want to escape a bad family situation at home, poverty and lack of information. However, some of these marriages have survived and have been productive. When a woman finds a person who will allow them to be themselves, pursue their dreams, try not to change them, has no budding parents, gives them the freedom to make mistakes and learn from them, showers them with love and understanding, and are willing to give their lives for them if necessary, then, and only then, will she go head first into the relationship and marriage. Even though it is not widely accepted and is still fought by many, including some women, women can and are using their freedom to choose a mate.
Wolves mate for life and protect their mates even though the mates are as good as they are.
The older a woman gets, the more she understands that it will be impossible for some one else to change them. Therefore, it is impossible for a woman to change a man. Marriage is not a competition, or ownership. It is an agreement to share our lives with someone else and do our best to improve others and ourselves. It is as simple as that.
