I agree, with you. When i was cheated on, i realised how superficial or relationship was, we wanted love but we didnt love - it was just loneliness. So it made it easier to walk away. But when there's a family built, many years of marriage involved, and when there are different circumstances one has to take into account and either move on or move away from betrayal. In the end, it has to be worked out, and there should be a commitment to talking it out and sorting this kind of thing so it doesnt repeat ever again. I know if this were to happen in a marriage, i would try work it out.
