Why do women get a free pass to be histrionic and overly dramatic without any personal responsibility?

I'm not a woman-hater by any means, but my ex-wife is a total basketcase and in spite of years of having tried to help her or get her help for her issues, I continue to be blamed for her neverending stream of psychological issues. She has anxiety, depression, eating disorders, addictions, OCD, you name it, this woman is riddled with it. I wasn't aware of it until we were married because somehow she was able to hide it whilst we were dating. During our marriage, which lasted 7 years, I begged, pleaded, demanded, and even forced her to seek treatment and she either refused, or purposely flunked out of whatever programme she was placed into. The final straw was one day when I caught her making herself puke *again* and when I told her she needed to go back to treatment she looked me right in the eye and then threw herself down the stairs. At that point I knew it was over because I didn't even feel sympathy, I was utterly outraged! I am done dealing with this freak. I am NOT the cause of her problems and I've done everything a human being could possibly to do try to help her, to no avail. And yet if I mention being concerned for my children, of whom I have to share custody with this loony, everyone jumps down my throat as if I'm evil for worrying about their well-being rather than "helping her get well". What about *her* responsibility in this?! Is she given a free pass for being a woman, or a free pass for being a total basketcase, or what?
