divorce because of Obamacare

So Obamacare has made health insurance for the working middle class unaffordable. I'm on my parents Cobra plan until the end of the year then that's it. Last year I looked into an Obamacare plan on the marketplace and I could not afford that $500 a month premium. A few years ago before Obamacare my husband's plan was $120 a month. That's affordable! Now he has health insurance through work and my kids are on Medicaid. That just leaves me without any. I'm contemplating legally divorcing my husband in order to afford Heathcare. I honestly don't know what other option I have. Has anyone done this or is planning on doing it? Thoughts?
