I think that all depends on the girl and how well you know her. Some people just don't accept advice very well. When I married an N, his father tried to warn me, but I didn't want to hear it. I'm older and smarter now. I just broke up with an N and was very grateful for the warnings I got this time from his closest friend. I was told to be careful and that he was a "problem child", and had problems staying in relationships with good women. It was hard to hear, but I was experiencing such a roller coaster of emotions and I really needed to get free. I needed someone else to confirm my suspicions, as he was so wonderful and seemed to be everything I wanted at first. If she is smart, she'll listen.
Yes but do so anonymously.
Tell him to go and leave you alone.
why not?
No, but, he will likely dump the girlfriend in time and move on to another victim. Trust me.
Just because this person is a narcissist doesn't make then much different than anyone else cheating with your spouse and you should be more concerned about your spouse cheating. By all means sit down with the narcissists spouse and tell the whole story, but be sure you have absolute proof before doing so. Don't be surprised if the narcissist's spouse becomes angry and is denial, but, in time the spouse will become to believe it.
I don't think they ever do cam down.
She should. If you want to date other women, it is best to divorce your wife. Then you can date, and be a decent person.
You should ignore them back and be thankful you are not in their circle of victims. Get on with your life and don't fret over not getting attention from a narcissist.
It is doubtful that a narcissist would be faithful for long to his girlfriend. They love themselves most of all and have trouble with long term relationships.
No, no narcissist pig, just a plain dumb insensitive one.
Because he is projecting how he feels about himself on her. It's as simple as that.
If a man has another girlfriend, he is already lying to his first girlfriend and he is most likely lying to his second girlfriend. The man does not care about or have respect either of them. This describes a narcissist. because they are evil
