The emotional maturity of a narcissistic person is similar to a 5-year-old child who pouts and refuses to play with his friend in the sandbox because his friend wants to share the pail and shovel. The 5-year-old refuses to talk with his friend and angrily storms off to play on the jungle gym with a different friend. The bewildered child with the pail and shovel feels confused, rejected, and does not understand why her friend can’t share. She just wanted to build a sand castle with him.
So how does one deal with silent treatment from a narcissistic person? Many therapists suggest that the survivor understand that the narcissistic person is incapable of a high level of empathy, reciprocity, and compromise. The silent treatment is a cruel form of emotional abuse that no one deserves nor should tolerate. If an individual experiences this absence of communication, it is a sure sign that he or she needs to move on and heal. The healing process can feel like mourning the loss of a relationship that did not really exist and was one-way in favor of the ego-massaging narcissistic person. The minute the partner disagrees with the narcissistic person or asserts his or her healthy boundaries, the narcissistic person deploys his or her arsenal of abuse tactics. Often, the silent treatment is one of his or her favorite weapons." - Andrea Schneider, LCSW
A lack of communication can lead to consistent negativity in interactions. Ineffective communication attempts tend to distress those involved, which can result in reciprocated negative exchanges. Overall, communication problems and the conflict that often results have been known to contribute to reduced relationship satisfaction and eventual breakup. Not being able to communicate effectively can make you feel incompatible with your partner or frustrated with the relationship in general.
IMO: I have been in an emotionally abusive relationship before and the first couple of times I brushed off the silent treatment emotional abuse and just thought men in this era don't know how to communicate unless it's via text message or some form of instant messenger. But, when I realized this person had a habit of giving the silent treatment whenever things didn't go their way or whenever they didn't know how to communicate or just wanted to "avoid conflict," I quickly realized that it was a problem and one that I was not willing to put up with. The silent treatment solves no problems it only creates more. If a person isn't mature enough to communicate their thoughts, feelings, or concerns to their partner in healthy manner and in a reasonable amount of time then that isn't the relationship that I want to be in.
Do not accept emotional abuse from anyone whether in a romantic relationship or not. It is important to know that you are worthy of a healthy relationship with someone who can communicate in a mature, emotionally healthy manner.
