Living with a Narcissist: Don't be a victim

Maybe you know someone with a Narcissistic Personality Disorder, also known as NPD. When you met them, they were charming and seemed to have it "all together". Always ready with an answer, which you perceived as knowledge. And yes, maybe this person is indeed knowledgeable. And then things start to go sour in your relationship. At first, it seems insignificant. A criticism cipher through here and there. The tone of their voice starts to change when they speak to you. But you put that warning light back in the box and shove it to the furthest part of your mind because you love them. But it does not change it becomes worse. You seem to not be able to do anything right in their eyes. You feel like you are walking on eggshells around them. You become more introverted because you start to see a pattern forming where whatever you have to say, would be disregarded no matter the validity of it. So, you keep quiet, and the resentment starts to emerge for the NPD in your life. Love, respect and the comradery that you had is replaced with a misjudgment and utter disappointment. Family and friends come to visit, and the NPD is as charming as he/she can be. People will tell them what a good and considering person they are. Boosting the already wonderful image, they have of themselves. And you can see the change in them, every day. The warning lights are flashing like a disco in your mind. Mistrust and fear creep in and fill you up to the rim. Are you living with a Narcissist?
