I think Zak missed the part of Christianity where they address pride. Well, Zak, you're lucky she's still with you. If I were in her shoes, I would have taken steps out the door without so much as a second look. You need her a lot more than you realize or are currently willing to admit.
And I find the fact that you think you know more than a member of the clergy about their religion to be the most obvious sign of your pride. It is honestly quite sad watching you turn into so much of an asshole. I like you a lot, but I don't like the person you are trying to turn yourself into one bit.
