^^I wouldn't either. But a few of those questions listed will probably be addressed by your priest or any good premarital counseling session. Such as
Q1. The money issue. All of us who are or were married knows that this will come up. I think it's important that a little time be spent addressing it.
Q2. Family. If one partner really wants a big family while the other really just wants a dog, wouldn't it be irresponsible to proceed with the marriage without first addressing this?
Q3. Care. I once broke up with a girl because on two occasions she neglected to offer me any of the food she had prepared and was eating in front of me. And we had been dating for four months. I surmised that if she was this selfish when we were dating, how would she behave in marriage?
Q5. Seems like a valid issue but you should be able to answer that yourself after observing a person for a while.
Q7 & 8. Very valid questions. Does your potential husband/wife shy away from the difficult issues of life? Do they tend to manipulate you into 'rescuing' them every time? This probably belies a deeper issue that will surface after marriage. Are you prepared emotionally, physically and financially to deal with it? What happens when you 'screw up'? Does your potential mate deal with it in a mature manner? Or do they become unreasonably angry, emotionally upset,... How a person deals with difficult problems and situations really is telling.
I didn't read the source, but the questions listed failed to mention 'religion'. This is a HUGE issue for most folks. And though it touched on family and problem solving, it failed to mention In-Laws. Another big issue. Lastly, studies show that along with money, sex is a big issue in a marriage. Sex isn't simply tied to the procreation aspect; there's also a physical and emotional aspect.
Again, though, I wouldn't base my decision solely on these questions. Nor would I trust only my interpretation of them. As an Orthodox Christian, you must seek the counsel of your spiritual father as well.
