In grade school I couldn't understand the purpose of history. Was it going to make the present better or make a bleak future exciting? Do we decide not to repeat it or find ways better for the next generation? Those questions weren't answered. It was just a barrage of facts or false documents for a group of children to believe who would rather still be playing at recess.
Is the attitude still there when we hear the past life of the person we are dating? How interesting is it? Does it change the present for the both of you? Will it make the future better or are you ready to get through it so you can go and "play"?
Actually, it should be fascinating to know if there is mental illness, alcohol or drug abuse, and a past of chronic smokers. Doctors ask these questions and more because they can determine the mortality of an individual. What they don't teach (well, not any doctors I have seen) is that family pre-determines the behavior of an indicvidual. If the behavior is mimicked then the outcome will be the same. If a mother chooses to smoke, drink, or uses drugs while pregnant, it changes the chemistry of the unborn child. The child already has the craving for whatever the vice the mother chose while pregnant. What is interesting is while it seems obvious (to me) the previous statement; in my research I didn't find how this could be true with the father. If the father abuses drugs or alcohol, doesn't his body chemistry change as well? In the semen, shouldn't there be a slight change as opposed to if he never abused drugs at all? Why is it that a child must see his father do the abusive behavior before having the desire to do it?
So with dating, wouldn't the physical attraction (or the body chemistry) change once realizing the past of another? If we use the Word stating that things old have passed away behold all thing become a new (2 Corinthians 5:17 KJV), would that make a difference in hearing what the person (or family) use to do before coming into the knowledge of the Truth? It actually shouldn't if your faith is intact; however, it does propose the question of the actual history of the person's faith. If rooted in God and nothing will move the other person from what is known of God - then the past is superfluous. The only purpose the past has would be to generate fear in that case (2 Timothy 1:7 KJV). Just like recovering addicts, it is expected in that recovery to have some relapses. Would this be true for those who have wallowed in the evil nature and it starts to call them back? In that case, relapses may really be interesting to hear about. Once heard, pray and make the decision. Personally, I would still choose life and remind God of His Word. Why would He order your steps in that direction (Psalms 37:23 KJV)? Shouldn't you delight in your way? It is written the blessings of the Lord maketh rich and He adds no sorrow with it (Proverbs 10:22 KJV). If your peace is troubled and you continue to date for the purpose of marriage (Proverbs 16:7 NIV), your future will be bleak. That is not Kingdom Living.
