Living together before marriage is clear disobedience to God. The evidence is that it does not work.
Today's modern couples think they are living smart, doing their research.
They buy houses together, funishing it and living like a married couple.
They figure if there is going to be problems in marriage, why not find out on a "trial" basis; no commitment, or most important no covinent between them.
If not satisfied go shop somewhere else.
Sudies have shown that living together lead only to non-commitment after marriage. The couple continues to look at marriage as disaposable.
Make this sacrifice for each other. Return to the old values from years ago., when this was unheard of.
It will be well worth it.
