Nowadays, it' s largely taken advantage of; the cheating rate for men wouldn't hover around 60% if they weren't taking advantage of their wives' loyalty...men have even boasted on this site about how most women will stay wit their husbands after they cheat..if that's not taking advantage of someone's loyalty and commitment, then what is? It's basically communicating "She loves me too much to leave me, so why not cheat since I can get away with it?"
The cheating rate for women is around 40%, and I recognize this before anyone accuses me of male-bashing. It's just as disgraceful when a woman does it. I just naturally, being a female, am more concerned with the male statistic.
But I certainly appreciate and value it, if it means anything. I think it's disgusting that not many people do nowadays.
