For example, a one night stand could just be a “meaningless fling” to the person committing the deed, but what if it has more long lasting and far-reaching consequences such as the contraction of a disease or the creation of a child? It also depends on who the one night stand was with. I would imagine for some spouses, it doesn’t matter who it was with. The unfaithfulness and act of betrayal – even if it only happened once – is enough to destroy trust. But for others, this could be an extenuating circumstance.
