A marriage is the union of two individuals and the union of two souls can be a blessing. Sometimes the outcome is not very satisfactory and the blessing can turn into a constant struggle. Every individual is different and when two people start a life together they can find some aspects of each other not very pleasant. The key to a successful marriage is to understand each other and find ways to strengthen a relationship. If the problems are not dealt with initially they can lead to disappointment, anger and depression, which are not healthy for your emotional well-being.
