I think my father's recently finalized divorce that took 2.5 years showed me not to count on getting money from a spouse. He filed within a month of his mother in law passing away and found himself not entitled to the inheritance.

I guess what I am trying to say is divorce because it's over. Sounds like even in marriage there's a sense of fiscal irresponsibility? You can consult with an attorney, which is certainly something I'd recommend. At the same time, prepare to live on whatever income you bring in.
