Hi Fresia,
We have some conversations here about what you're going through -- whether it's better or not to stay for the kids, whether we've had enough. It's a tough decision, and I wanted to share this thread because you will learn that you're not alone, and many people have weighed in on their own struggle to answer this for themselves:
PERSPECTIVES: Is it better for the kids if I stay or leave? (click on the green link to read)
There have been studies that show that kids who grow up in divorced homes have more problems in life than kids whose parents stay together. Would having a BPD/NPD parent (or other abusive parent) change this outlook? If you leave, do you think your kids have been harmed by the friction between you and the ex? Would things be better for your kids living in a two-parent home situation? If you are the father, do you believe that leaving your marriage means leaving your kids?
We also have a good article about the psychological and emotional aspects of divorce. Understanding the emotional experience you're going through, as well as that of your partner, will help you support your son.
Psychological and Emotional Aspects of DivorceARTICLE: Emotional Stages of DivorceThe decision to end a relationship can be traumatic, chaotic, and filled with contradictory emotions. There are also specific feelings, attitudes, and dynamics associated with whether one is in the role of the initiator or the receiver of the decision to breakup. For example, it is not unusual for the initiator to experience fear, relief, distance, impatience, resentment, doubt, and guilt. Likewise, when a party has not initiated the divorce, they may feel shock, betrayal, loss of control, victimization, decreased self esteem, insecurity, anger, a desire to "get even," and wishes to reconcile.
I also learned the long, round-about very mistake-laden way that validation is where my son's healing was grounded. It is easy to do, has an immediate effect, and also takes a while to master. We have a really helpful set of articles about this here:

It is difficult to be in these relationships, and difficult to end them. And raising a child we love who has a mentally ill parent -- it's a lot. You're not alone, and we're here for you.
