Hi Sylvie,
On the question of whether we are at fault for getting hooked unto a P, there are, just as you mention, different schools of thought.
As far as I am concerned, we are who we are by virtue of nature and nurture. Our eyes are blue or brown, our skin is light or dark, we are tall or short and no one is going to say anything other than that is nature, i.e., genetics. By virtue of nature AND nurture some of us are soft spoken and gentle, others loud and temperamental and so on. Some of us are very nurturing with other people while some of us are more predisposed to minding our own business.
I do not think that it need be a negative personaility trait that attacts a P. For example, strong, very capable and nurturing women can be just the thing to attact a needy P. Being strong, capable and nurturing is not a negative characteristic. Being a well-to-do business woman can also be an attractive trait for a P who is out to get a little economic freedom on such a woman's tails.
As you know yourself, a P can be a chameleon, who knows just how to appeal to whatever characterics we have. A P is very good at reading other people and honing on on the one aspect where a person is in need of support, love and care.
We all need support, love and care, and some of us manage to get the right amount of erach from work and family, but most of us are lacking in those departments. It need not be something that bother us or make our lives difficult in any way, it may simply be that we know that a little more of those things would fall on a dry spot and when it is offered to us by a seemingly caring, intelligent, attractive ,supportive and accomplished person, why would we say, 'No thanks!'. It's almost too good to be true and such nice men don't grow on trees.
You write:
"I just want to figure out if I and others need to develop a more scaly exterior going forward and nip these things in the bud before they spin out of control. "
Yes, I think we would wise to figure out what in our make-up that attracted a P in the first place. Perhaps, we need to be tougher in certain areas. The strong and capable need to realise that they cannot save the world and those of us who are aware that we are (were) lacking love and support, can learn to be more realistic about where such can be found without compromising the Self.
If everyone was like H.H. Dalai Lama, there would be no need for such an enlightened being to exist - he would be superflourous.
As far as I understand the Dalai Lama, his message is that we must practice compassion - and what better place to start than with our Selves.
Take care,
Nan
