I was earning about 65% of our HHI before I quit to SAH last year. DH finished school and got a great promotion, but still doesn't make what I was making.
I make about 60% of the HHI. My next promotion should have me almost lap DH. DH does earn OT, whereas I'll take the comp time instead.
DH knew I was on a bigger career trajectory than him when we met. It's really nbd for us, although many people are always amazed when they find out around here.
I make over 60% and my job is not optional but his is. I also have a lot more earning potential long term. He can retire fully at 48 though so that is a huge benefit of his job.
