I don't think onlookers realise the emotional and psychological hold these men (or women) have over us, hence the 'why don't you just leave' statement. I can't even begin to describe it of fully understand it myself. The best way I can explain my experience is to describe it at as erosion and dependence, which then instilled fear and was fleshed out with bouts of extreme kindness.
He slowly and subvertly chipped away at my confidence around others, tiny remarks about my personality or ability to fit in that summed up to this - 'you are awkward in social situations, people don't like or want to know you, but I do, and I'm saying this because I love you and don't want you to be hurt.'
And so he successfully eroded my self esteem and I became dependent on him for my 'boost'.
He would then leave or threaten to leave if I 'stepped out of line', throwing me into a panic, begging him to come home/stay because 'no one else would want me.' (see erosion of self esteem).
When I was pregnant with DD1, we discussed me leaving my part time job and being a full time mum. At the time it appeared he wanted the 'traditional' family and although I was hesitant, I agreed.
Cue complete financial dependence on him. It was only after DD1 was born and I got ctc and cb in my name that I realised how financially controlled I'd been.
These abusive people successfully turn themselves into a drug that even though you know it's bad, you can't seem to escape from. It seems to be a mixture of manipulation, emotional blackmail and very cleverly calculated burst of sweet, kind behaviour.
There were many straws that finally accumulated to a whole hay stack and I finally walked.
He still attempts to control and manipulate from afar but his hold is getting weaker and weaker the stronger and happier I become. He has lost and I have my life back.
My parents were fond of saying 'just chuck him out' or 'don't take him back' or 'just leave'. If only I could've communicated why I didn't do it earlier. Even now I've left they still consider me weak for waiting so long, which makes me so sad.
