It depends on the individual and her specific background, but for instance for girls of mothers that suffered from domestic violence there's a very high probability they'll end up with a violent husband, even though they keep telling themselves that they won't. Forgot how this syndrome was called, and this iPad is awful for doing Google searches.

Basically we are doomed to repeat many of same mistakes as our parents. You do have a certain control over your life, but eternal vigilance and self-awareness is required. I keep seeing this every day, as I'm now a father too. For example my father was a workaholic that didn't have much time for me. He was also very critical of other people's mistakes. I tend to repeat these same mistakes, even though I make an effort not to, but sometimes I just can't help myself.

It really depends on the individual though. I have at least one friend coming from a broken home and he's one of the most balanced individuals I know.
