ihear, are you kidding? Are we talking about running a red light? Mistake is a very nice name for sins but get real. Who you are now is made from who you were. And regardless of any reason the guy would want to know, a person’s history defines the person. One day you are married to this innocent person. The next day you find out that this very nice person duped you.
I know this makes no sense to you from this perspective so let’s look at it from another viewpoint. Imagine this real open-minded guy agrees to marry you. Three years later he finds out that you witheld this information and he is totally fine with that. He even goes on and on about how it doesn’t make a difference what you did in the past. Then you find out why. It turns out that he killed three people and threatened another two. But the next year on Yom Kippur he “saw the light”. He never cried like that before. He decided right then and there that he’ll run away, change his identity, and enroll in Yeshiva. He’s Mamesh a Mentch and a real Baal Teshuva. Besides for his obcession with sleeping with a weapon and always living near a border, he’s completely normal, and most important, a wonderful father.
Will you smile just as before, or better?
