Triple Murder suicide.

So a confirmed affair leads to wife killing her children? Then she realizes RIGHT as they're about to head into the water that she made a terrible mistake? Good grief, whatever the hell happened to just filing a divorce? Now the kid's going to grow up all messed up because he thinks it's all his fault that his brothers and sisters are dead. I blame the father for being unfaithful, but good god the wife went overboard on her reaction to the problem. Ugh.....
