Problems with compatibility may lead to divorce, in which case both parties accept responsibility for what occurred but are usually able to maintain a positive post-divorce relationship. In other cases, one spouse may have behaved in a toxic way, and may sill behave in this manner even though you’re separated. Prevention offers a few of the signs of narcissistic personality disorder, which can have a disastrous impact on a relationship.

True narcissists tend to have problems with self-esteem and self-image. Unlike most people with these issues, who express insecurity as a result, narcissists supplement their poor self-image with an overly confident, boastful demeanor. While this may seem positive, it can be difficult to deal with a narcissist unless you’re offering a continuous flow of praise and admiration. Anything less will be taken as an insult, which leads to a lot of conflict.

More damaging is the narcissist’s lack of empath towards others. They have a difficult time supporting others emotionally in their time of need, but expect full, unconditional support when they’re having issues. They’re also prone to making insensitive statements about a person, and often can’t understand why someone would take offense to these statements.

So, what can you do if you’re faced with a narcissist? Setting boundaries is crucial, especially when you share a child with the person. While it can be difficult, don’t fall into the trap of being manipulated; instead, stand your ground and establish what you expect from the relationship going forward. When poor behavior involves your child, it’s important to provide loving, unconditional support to establish the proper way to treat those you love. And if the problem involves visitation or child support, take the matter up with your attorney.
