sweetexpectation - I can confirm that my experience is that my NPD H has always been my enemy and he has continually stated that he wants to destroy me.
And the way our relationship was set up from the start was - he continually threatened to leave me, I used to (not any more) beg him not to leave me and that is the way the power worked. I had none. And, of course, if I said I would leave him - he would say - so what, I don't care.
Now, though, he would never leave 'his' house.
And, another tactic he has used with me has always been - if you have emotions as a person (and needs) that makes you a 'weak' person, whereas he is 'strong'. He has told me I am 'weak' continually and he did brainwash me to believe it - even though, in addition to all the stress and trouble he has caused me, I have had other physical problems to do with having babies to recover from (with no help from him at those times of a practical nature which I really needed post-operatively - thank goodness for my mum at those times), while he has not had a rough time, and yet apparently I was the 'weak' one.
Ignoring another person is a very effective nasty manipulative weapon if it is done long term also.
I am now in counselling trying to get some self-belief and confidence back, in addition to doing other things to build myself up again.
I did work out, bullies are cowards - they are not strong.
