For many couples, premarital counseling works to help the couple identify any potential compatibility problems that may arise in the future. It can help couples improve their communication skills and learn to get better at managing conflict.
These types of skills are important in any type of relationship, so if it's the couple's goal to get married and stay married, premarital counseling can give them a better shot at success. It's important to remember that when two people get married, they are trying to join together their values while still staying true to themselves.
Each person deals with roadblocks in life differently, and it's important for two people to learn to work together in harmony before they commit to spending the rest of their lives together.
