The Narcissistic Relationship Checklist
When you are engaged in a relationship - any kind of realtionship - you get to deal with other people. There is a roughly 1% chance that you have to deal with a pure narcissistic personality. But there is a much bigger chance that you get to deal with someone that will display unhealthy narcissistic behavior.
To check if the person you are dealing with could be a Narcissist there is a list of question on the right here. Some questions may not be applicable to the relation you are in with this person, that's quite okay.
The idea about this list is the following: If you answer one question from the list with "yes" the person could be narcissistic. The more often you answer a question with "Yes" the more likely it is that the person you are dealing with is a Narcissists.
Please be careful. This list is not a tool for diagnoses. You may never draw the conclusion that someone has an illness or a disorder unless you are licenced to do so and have gone though the proper diagnostic processes. This list is no such thing.
