Is divorce tougher on boys?

I was reading here that divorce may be tougher on boys. They have done a study that basically suggests that because moms tend to be the ones who get custody of the kids, boys tend to wind up without that male influence and male bond in their lives and so they end up having a tougher time than girls handling the breakup. This obviously impacts their behavior, academic performance, social skills and a host of other issues and problems. So, another reason to hang on to the marriage to the bitter end. To save your sons.
