The support factor should not keep you there if there is nothing left to keep the marriage together. If you're sure, then get a divorce, and I don't know the laws of your state but if you're unable to support yourself there is Alimony or what some states call "spousal support" In my state it depends on if the supporting spouse has been the sole source of income for the dependent spouse and also the length of the marriage comes into play in deciding this. One other thing is that if there is any infidelity on the part of the dependent spouse, that will usually nullify the validity of the claim for spousal support. In other words if you had cheated, you'd be exampt from this claim. (depending on the state, I think that matters only in some cases) My point being that you can get support, most likely if you divorce him.
