How does a Narcissist react when a Source he has started devaluing totally avoids and ignores him?

This again depends on how severe the disorder is, and other elements of the person's disorder AND also how long the relationship has lasted etc. To those who are absolutely convinced that someone - anyone - with a personality disorder is completely incapable of having feelings for others, I would remind you that to be diagnosed, one only has to meet some of the criteria, not all. I only mention this because I have noticed that there is a tendency for some people to depersonalize those with personality disorders and I assure you, many can function fine in society (yes, narcissists can be capable of empathy - lack of empathy is only one criterion and he/she may not have that among his/her constellation of symptoms). Having said that, yes it is possible a narcissist will have "other people to use", but this is not always the case. Depending on a lot of factors, a narcissist could also become quite upset with the lack of attention and try very hard to get that person to attend to him/her again. If the relationship is over, it is possible the narcissist will try to re-connect, and I cannot tell you how many people I have treated who have experienced this. From "normal" people also!

AnswerThey always have others waiting in the wings. They are resourcefull people and will be creative to find other people to use. answerThey pout like a six year old that has been sent to sit in the corner. N's do feel guilt and know they are playing games with you. They will begin to worry what you think of them and try desperately to get you to notice them. But remember they dont think anything of you - they just want you to think of them.
