Have you ever heard someone say the point of marriage is happiness? You got married believing the purpose of your spouse is only to make you happy? I just can’t believe you reached whatever age you are at with such a naive view of life.
The question has already been raised, but you have not responded on point. Do you believe that marriage between brother and sister, or father and daughter, or mother and son should be legal? If not, why not?
