There's only one problem with this. Premarital sex has clear moral ramifications. It's a sin. Taking a job transfer "can" be a morally neutral decision over which two people disagree about what is best for the family.
If one person is holding to his decision for purely personal and selfish reasons, then I would say that does have moral ramifications. However, not every decision in life is a black and white, moral decision.
True, but in every mutually exclusive choice, G-d does know which is the best choice to make.
Shalom.
