I am assuming that you are asking for conflict resolution which involves listening to problems from both partners.
If there are many issues, small issues can be taken first to bring some cooperation and peace.
Hidden expectations from each other are discussed at length and how much another partner is willing to provide and adjust to a partner’s demand and expectations is planned. The couple is encouraged to talk about their emotional hurts and pains. Partners become aware of their own intentional and unintentional mistakes.
They are encouraged to spend special time with each other without bringing the issues at that time, which helps them to feel love for each other once again.
New strategies are discussed to deal with the day to day routine and for the problem areas with the approval and consent of both partners.
Behavior modification techniques which include habit correction, Thought replacement, Healing Therapy, etc are also implied wherever necessary.
Anxiety, fear, rejection, mental and physical health-related issues are taken care of.
The entire process is to make the couple empowered to bring their own solutions that work for both partners and to bring love and affinity in a marital relationship. The sole purpose is to make the couple adjust to the family environment and to bring change in oneself to suit the purpose.
