Elsa, sorry if you addressed this previously, but have you consulted a L? There are formulas that vary by state for child support and alimony. In my state, alimony varies by number of years you've been married -I qualify for "permanent". I've also been told by both Ls I consulted that there's no need for me to change my job to a higher income if I don't want to. If you haven't already, get some advice on this, get a good handle on your assets, expenses, income, and what a court might order. It will make you feel better, and give you an idea of how to structure things now.
Don't be afraid or ashamed that H has to pay more than you do. I personally made choices that supported my H's career, not mine, and those choices also allowed me flexibility that made our family life better for our kids. As a result, he makes 4-5 times what I do, and if it comes time to split things legally, I'll happily accept my share of his income each and every month. I earned it.
