My parents’ main priority was each other. That’s not to say we were unloved or neglected, but their marriage was the rock around which the family revolved. I think they would have been perfectly happy together even if they never had children. Probably happier, even. 
I don’t know if we’ll have kids yet, but that’s an example I try to follow in my own marriage.
I’d die for my kids, but I live for my wife.
With all due respect, I don’t agree with this at all. I love my kids, but I don’t think it’s my job to put them above my spouse or me. My husband and I will always sit at the head of the table. We will sit in the front seat of the car and the children will sit in the back. We will save up for our retirement, and if we have enough left over, we will help them pay for their college.
My husband was not demoted when we had children. He was promoted from "husband’ to “husband and father.”
