I think with respect Seeker that often women feel unable to leave these men because socially we are judged fairly harshly for doing so, particularly if we have got children with them.
I refuse to put up with shitty behaviour but then when this happens, if it does, somewhere along the line when you're already up the duff or you've got kids, you find yourself caught in the trap between staying put and 'working' on whatever you can salvage, or leaving, reclaiming your life and then having to put up with people looking at you with a mixture of pity, embarrassment and confusion when you tell them that your child's father was a dick and you decided enough was enough.
It is not nice being a social pariah
In fact it is tempting to tell no one but your closest friends
but people find out anyway and then they just talk about you instead of to you, and it makes no difference.
Men who make our lives miserable are usually 'normal' to begin with...mine was normal, strong, emotionally sound, funny, kind and protective. And sober.
When I was a few weeks pregnant he started to show his other side which is characterised by drunkenness, emotional hyperbole and suspicion of me to the extent that if I am out for any length of time (we do not live together) he will time me and become very angry.
I would ot stay in a life such as this, but to leave has been very very hard.
I can almost see why people stay, and compromise themselves totally. I am lucky to be accustomed to being a social pariah so for me this is part and parcel...I left anyway.
