I think the problem is that we humans typically think in terms of "right" and "wrong" when in reality these are merely choices. We can choose to stay in a difficult relationship or we can choose to leave. I believe that in many cases we tend to lay the blame for unwanted outcomes at the feet of others when in fact we chose the path that brought us to those places. It's an excellent way to avoid dealing with the issues that are present... and how certain negative themes keep coming up in our lives: we chose them.
