They do exist in many guises, and seem to latch on to the victims' neediness and weak spots in an instant.
A friend of mine is a highly experienced and shrewd mental health nurse, but, like all of us, has her buttons that can be pressed.
Her ex-husband and ex (ish) boyfriend both pulled a string of stunts on her that were fantastically manipulative and damaging, and I was shocked to see how she defended them and at times excused the situation.
With her ex-bf, my partner and I went to their house for a meal, my friend H is a wonderful host and cook, the bf just sulked, resented having to turn his prog-rock music down to allow conversation to take place. He had cooked one part of the meal, supposedly a Thai dish with peanuts, it was awful, like slurry and tasteless, H simpered and praised it. The whole evening was awful, it was terrible to see a vibrant intelligent woman ''allowing'' herself to be treated in this way.
Whilst not as dramatic as many examples (and others that H went through with her ex husband) it highlighted the way the boyfriend used his manipulation to entrap her...we talked over dinner about other places H could visit, even down to other amenity tips, and BF uttered the dread words....''Why do you want to leave Bognor, everything you would ever want is in Bognor..with me''
Days later she visited us and asked what we thought of the evening, so I told her she reminded me of a battered woman defending her abuser.That started a chain of events which ended with six friends helping her move out whilst BF was...er.. otherwise detained in the spare bedroom by two rugby playing chums.
Rage and stalking ensued for months, and eventually she started seeing him again..''he's not that bad...he means well..'' and his isolating behaviour started again.Luckily H's daughters intervened and said them or him, and so far she has steered clear.
These people can be immensely powerful and seductive, and we very often don't want to admit to being taken in.
