Man I just read all these posts and with me sharing the sickness may I add that he has his teeth so far in that it's pretty friggin simple. You have all the answers and yet you come back pay his child support and continue the circle which he has completely created for you to live by. You stand zero chance for happiness or self meaning at all. The classic push and pull is the only strength you have and really that's all part of his game. Fact is when you argue back your making it more interesting. Like when a cat is starring at the mouse not moving he sits and watches. When it runs is when the fun begins. Same deal here, when you fight you are allowing him to strengthen his game each time. Each time this happens it also weakens you more and more. You have one play which is to leave him and that's it. Anything else and you stand zero chance and soon enough you will completely lose yourself!!! I just shared the TRUTH and they say someone with NPD has no empathy, guess what I just showed it!!! Maybe me being here helps me more.....
All the best,
