If the couple is struggling with a lack of communication, it is important to understand the reasons why.
For some couples, they have a tremendous amount of potential but one of both members of the relationship are simply not investing in each other and sharing or talking enough. This may be because of past habits they are repeating, or because of some bad habits they picked up during their relationship. IT could also be because of the demands their jobs, kids, or family place on their day; they simply don’t have enough time or energy for each other. If this is the case, a couples counselor can help the couple learn and integrate those communication skills they have otherwise forgotten.
For some couples, they lack communication because their is not enough trust or desire between them. Perhaps they are communicating exactly what they intend; leave me alone. If this is the case, then the couple needs significant repair of whatever has been plaguing their relationship.
Whatever the reason, lack of communication can be fixed if the couple wants it to be fixed.
