I am glad things ultimately worked out for you and your daughter. I just don't know what is wrong with some people. My sister also has a penchant for marrying losers-one of which raped her daughter. Thank God that creep is out of the picture now, but how my niece can still call my sister "mom" is beyond me.
At the time none of us knew exactly what was going on, but it was obvious something was wrong. Social services was called a number of times, but they were useless. One caseworker thought there was merit in taking the children out of the home, but her insane supervisor thought a bad father was better than none at all. And it didn't help that my crazy sister covered for this freak.
I don't know about the "Borderline Mother" book that someone mentioned. My sister is nothing like my mother who would never have allowed one of her children to be abused by a pedophile. Nor would I. Neither of my nieces with children show their own mother's lack of judgement/parenting skills either.
It took years before my niece told us what happened. Trust me, my mom did not just pretend nothing had happened as my sister wanted to do. What is so ironic about the whole thing is that my parents would have gladly raised my niece. In the end, she was dumped on them at 16 when my sister married yet another loser.
Well, my sister is out of the baby making biz now and her kids are grown so marry all the losers you want!
