I agree completely with Bug's answer; she and I are pretty much in the same boat and on the same page.
My husband works out of the house full-time, I have my own freelance editorial business/am a SAHM. Don't make a lot, mostly fun spending money, but always with the option to take on more work. I have my own retirement account through Thrivent, my own life insurance, my own credit card, credit cards in my name secondary on his account(s) (which still show up on my checking account status), my car is in my own name, my own business account at the bank, I have a 4-year college degree, and am currently looking into taking classes in a new area that I'm thinking of going into (holistic health) so that I can open a business (my daughter is in the 7th grade now, so I can start thinking of other business opportunities). We have instant access to cash through extra money stored in our checking account as well as our savings account. I'm not sure about your bank, but our bank makes it almost impossible to either deposit or take out huge sums of money without the other person on the account being notified or having to sign for the transaction to be completed (this can get so frustrating at times when trying to deposit large deposits in my husband's name; I have to also sign the back of the check).
My husband and I otherwise have everything joint. I do the checkbook and pay the bills; I know where our money is going. I don't ever anticipate that something would go wrong between the two of us, like divorce, but if it did, I would expect and pursue alimony and child support (and my husband would not quibble on those), and I have kept my skills up so that I don't have any doubts I'd be able to get a full-time job to support myself/my daughter (ditto if my husband were to unexpectedly die).
I try to concentrate on good thoughts and not what-ifs. I don't want to bring in bad vibes and add them to the mixture/stir up the pot, when it doesn't need stirring. I have never felt as if I couldn't take care of myself.
