Is there a scientific link between acting-out and Shalom Bayis?
I don't know about scientific, but I have found that Rabbi Arush's book, The Garden of Peace, is absolutely right when he says that the wife is the spiritual mirror of her husband.
I can come home and be the nicest, most wonderful husband... and even take out the trash, wash the dishes, fix the broken light sockets, etc... but if I was acting out or ogling other women that day,my wife will usually start an argument with something like "why don't you do what you are supposed to be doing?"
The voice of Hashem! All she has to do is move her lips.
Think about this and tell me if you notice it too: The way our wives act toward us is the way we are acting toward Hashem.
Ouch!
