Yes, but only if he got something out of it.
Yes. Otherwise they'll get deeper and deeper into it. At lease they have a fighting chance if you tell them.
There's no way to tell. You must ask the person. Or better yet, leave them be.
No. Their narcissism would prevent them from it. It would mean they have a problem and as far as the narcissist is concerned they have no problems but the rest of the world that has the problems.
Narcissism defines an individual who believes themselves to be great and amazing, they may also belive others find them to be a great individual, anyone who does not believe this the narcissist may think has "issues"
The question I have for you is why would you want to do this? I understand that you think that this narcissist is bad news, but your question specifies the other person involved is "willing". Perhaps you do not understand the dynamics of the relationship properly. Maybe you are meddling where you shouldn't. Take a look at your reasons for doing this before proceeding. I understand what you are asking since I used to be one of those "willing" victims who was dazzled by the narcissist's charm. Lots of people did try to warn me that I was being used, but I was too much in the thrall of the narcissist. It took 8 years and 2 divorces before I came to my senses. Sadly I don't think you yourself can save the victim of a narcissist. The victim has to save themselves. You can tell them what you know during a time when they seem willing to listen, and hope they will eventually save themselves. Most do eventually get out. It is easy to get away from a narcissist once the charm wears thin and you finally see through them. The more frequently the victims hear the truth from others, the more likely they will get out sooner. When they finally do get out, they will be a lot wiser. Personal boundaries might be a good neutral topic to discuss with the victim of a narcissist, since that is one area where a narcissist runs rampant over his victim. If the victim realized how much his/her personal boundaries are being ignored, the victim could begin to put two and two together.
He loves himself more. Are you sure you want a commitment from a narcissist? He is not ready for a commitment. You need to decide for yourself how long you want to stay in the relationship without a commitment.
A narcissist and more extreme would be psychopath

Eventually, he'll tell you.
A female narcissist may tell a man she loves him for various reasons. It could be part of her manipulation and control tactics to keep him hooked and dependent on her. It could also be a way for her to boost her ego and receive admiration and validation from him. Ultimately, it is important to be cautious and aware of the potential manipulative motives behind her words.
It's not best to tell him after a while so be straight and tell him
Yes. Otherwise they'll get deeper and deeper into it. At lease they have a fighting chance if you tell them.
Maybe he doesn't really know that he loves you.
The most likely reason is that he loves the girl.
