I was married almost 30 years and didn't work outside the home. though I did go back to school for a teacher's license when my kids were in HS, unfortunately I became sick and was unable to get a classroom though I did substitute for a while. I was diagnosed with bipolar during my first attempt at student teaching after a breakdown. So, I know what you mean about getting a job, trying to make a career after all that time homemaking.
Unfortunately because I spent my working years raising humans I don't qualify for disability. In my separation agreement I get half of my ex's military retirement and I also get a certain amount in alimony that will continue until we reach SS retirement age (assuming it exists at that time!). If things don't work out, which I do hope they do, make sure you get alimony, you are entitled to part of any retirement accounts as well. my state is not a 50/50 state, it is equitable distribution. the bad part is...you have a share in debts as well. I gave up part of my share of the retirement accounts in order to make up that difference, I had no other money to use as I had no real assets.

my best advice is to talk to a divorce lawyer just to get information, there's a lot of information you need. also a lot of websites that can help. I'm only trying to look out for you in case your husband decides to follow through, you don't want to be blindsided.
basically what I discovered about divorce is that it is fundamentally a business transaction. so you need to be a smart businesswoman.
