While findings have concluded that children of divorced parents can have successful marriages, if their communication skills are poor and attitudes toward marriage are negative, they will need to develop the proper skills to succeed. There are real strategies for improving relationships and developing committed, long-lasting and happy marriages – but it does not happen magically. Individuals must be ready to change and improve their attitudes about marriage and relationships skills.
You seem to be afraid of making the leap into marriage. Is it because you fear divorce, or do you subconsciously feel that you are emotionally unready for a healthy relationship? You may be helped by seeking therapy so you can work through your past and work on cultivating positive and healthy relationships. Hatzlachah!
