Yeah... I should probably clarify.

When I say that I'm uncomfortable with the idea of my husband supporting me 100%, I mean in the long term.
When I was out of work a couple of years ago, my husband pretty much did support me for a few months until I found a consulting gig (I was collecting unemployment, but an unemployment check doesn't go very far!). But that was temporary and involuntary. It's also part of being married - you look out for each other when sh** happens.
But I'm uncomfortable with the idea of being a stay at home wife/mom for any length of time. There are many reasons for this, and I'm sure I've bored you all to tears with them

but from the financial angle, I know that if something were to happen with my marriage, I wouldn't have to run out and get a job (possibly in a difficult economy) because I'd already have one. I wouldn't have to rely on life insurance or on alimony checks that might not materialize. Not only that, but one risk of being a SAHM and later re-entering the workforce is that you have a hole several years long in your resume. And in some fields (like mine - IT) if your knowledge is not current, you're sunk.
But that's me. Everyone has to make the decision that's right for them. I commend AXOjen and other SAHMs, but I could never be one myself.
