its true a girl should know these things before she gets married BUT if she has the best personality, loves jah with her heart, and you're totally attracted to her and she can't cook, you shouldn't bypass her, you can always learn to cook but you can never just "learn" a great personality....
Now if she doesn't have the greatest personality, can't cook, doesn't clean, she's either a slob or a diva and you want to stay away from both of those types!
