To start with, it would be helpful to define what narcissist means, because it has a specific psychological definition.
As I understand that definition, I don't think narcissists discriminate as to whom they act upon. After all, it is all about themselves, not who they act upon. And self sacrificing people attract all kinds of people because of their concern for all others.
I would expect that people with poor self esteem tend not to attract many people, as that way of being tends to be off-putting.
It would be to whom those w/poor self esteem are attracted that may be the queston, and they are likely attracted to dominant types to help them. They might also be attracted to others with lower self esteem who they can help or dominate, as the case may be.
So I don't think narcissists are attracted to a particular type and that you may have had a string of unfortunate luck.
Here is the definition of narcissists I experience -
A person who wants every single person in the room of a party or school or church or shop or anywhere to think they are the most beautiful and interesting person there to look at and talk to and praise and pay attention to. A person who is extremely outraged and sick at the thought that there may be someone out there who is younger, smarter, wealthier, a better cook or better father, mother. Extremely bothered by the potential that someone out there may be liked more than them. They are terrible parents. They want so much attention they cant handle the youth and looks and love and happiness of their children and they try to bring the spotlight back to them and the ppl they attract and how amazing they think they were when they were kids too. The narc will get jealous of the kid's dating period and the sports and hobbies they are involved in because once again, the attention is not on them. The narc talks about themselves a lot. They are also hugely detrimental to their kids because instead of their kids being nurtured and loved and brought up to grow and learn for themselves, they are taught by the narc parent to spend all of their time and energy thinking about the narc. To serve the narc and to have the narcs best interests met. It is true that for some periods the parent will show what looks like love and care by buying the kids something nice, but it is only right before showing off to other ppl to show how apparently successful they are. The children of narcs suffer and as someone here mentioned they end up having intimacy issues and difficulty relating to others because they were trained to pay all attention to the narc or suffer greatly. The obsession of the narc is huge. I'm sure I have more to add but this is what pops out at me this time.
Now, to answer your question as to why I attract them - firstly, I'm extremely repulsed by them because I can see their false actions in their aim to get attention. That doesn't work with me. You cant fake it to get my attention, you have to be genuine, which a narc cant do. But maybe I'm here to teach them this. A lot of the times I see narcs doing bad behaviour to get attention and once again, I don't believe in rewarding them with attention if it is a bad behaviour. And funny enough, my son has taken after my mother in law (a narc) and we are working on his behaviour with the speech therapist and it is doing wonders. Now, back to what I was saying, Narcs hate me because 'I don't give them the attention they so desperately crave.' So that's why they keep chasing me. All these narcs in my life are in my 1st house. And me and my mum and brother and cousins are in the 12th house.
On the topic of self esteem, in my personal opinion I find narcs to have low self esteem because I think that if a person needs that much attention and needs to talk so much about themselves, then they are insecure. However at university they told me the opposite. They said that ppl who talk about themselves on a regular basis have high self esteem. Well, I just cant help but see the weakness. Maybe other ppl are fooled but I can see the weakness clearly.
