Splitting time between cities?

My husband recently had an offer for his dream job but ... it would move us from LA to Denver. It's an incredible opportunity, and I don't want him to pass it up. However, my job (which I love and just got promoted!) is in LA. I work in entertainment so LA is kind of a must. He is also incredibly supportive of my career ambitions. So we're stuck. We're thinking of figuring out how we can split our time between LA and Denver. Has anyone ever done this? Do you have any advice? THANK YOU!
