If you did pursue a divorce, you will most likely stll get the benefit of depending on his salary in the form of alimony (
support for you) and child
support (
for the kids). They are two separate financial obligations that he is legally bound to make.
I am not one to recommend divorce, so that's not the route I'm suggesting you take. I just wanted to point out that if your circumstances led to divorce, you have the potential, with the right divorce lawyer, to still depend on his salary.
