I lived with an abusive twat for years, and now sadly i have a freind whos married to an abusive twat.
I dont think pointing out that shes being abused will help. Its likeley she knows that already and has a wide range of excuses available for him, ie he didnt mean it, hes stressed, or worse, its my fault, i make him do it ect.
I genuineley didnt know i was being abused, and if someone had pointed it out i wouldve assumed it was my fault. More than anything, my sense of denial, and that of my freinds, is so great, that i just wouldnt have it.
There is nothing more painfull than acknowledging that you have married a man who doesnt love you, and worse, who enjoys hurting you. Many women will do anything to avoid knowing this , in some ways it wouldve been less painfull to carry on being abused than to realise i have wasted years with an abusive wanker.
My advice is if she calls you with a example of his bad behaviour, do not focus on his behaviour, dont let it all be about he said this and what a nob he is. Focus on how she feels. If you tell her hes a prick and she shouldnt put up with him , it will only add to her low self esteem and she needs the opposite. Avoid saying " i would do this ect ", perhaps instead, how do you feel about that ect.
Very very difficult, breaks my heart to hear about my freind being abused in this way.She knows the ins and outs of my marriage, recognises the abuse of others , i have given her my famous lundy book, yet still, as far as she is concerned, she is not being abused.
