Does my Ex’s New Husband’s income factor into child support?

I’ve been paying my ex child support for our two kids since we divorce. In the last year, she’s remarried to a very wealthy guy and now my kids live in a huge house with him and get just about everything they want. My ex even quit her job because she no longer needs to work. I’m struggling to meet my own family’s needs while still paying her child support for the kids. It makes no sense that she’s still taking my money when our kids clearly no longer need it. Does her husband’s income count at all in the calculation of my child support? Is there anything I can do based on these circumstances to reduce or stop my child support?
