But to some of the rest of the questions, in my humble opinion, it goes to the background of the person.
If a person grew up in a home where mom got what she wanted by pouting and manipulating, and daddy gave in to it, then that is what the person will think is normal. That is how they have been taught to handle things.
Sometimes I wonder, not being a parent myself yet, if parents understand that everything they do is teaching their children how to treat thier future spouses.
Have you met her parents? That will probably answer a lot of your questions right there. The other questions will be answered by "How much quality Word training is she getting?" if she is taught to be a child by her church, she may very well think that is the way she is supposed to be acting.
Quick analogy. A young man noticed that before his wife cooked a ham she would always cut it in half first and then put it in the pot. One day he asked, "Honey, why do you cut the ham in half first before you put it in the pot?" She thought a while and said, "I don't know, this is the way my Mom always did it. If you want to know, you'll have to ask her."
Next Christmas, he asked his mother in law. She thought a while, then said, "When I was a young bride, all we had was one pot and it wasn't big enough to hold the ham unless I cut it in half and rearranged it in the pot. Your wife just learned form my bad habits."
