Thankfully the person I married is far more willing to face my ambitions and discuss compromises and other options. We've run the gamut from me pursuing med school to SAHM-hood (and SAHD for him, too) - which, despite society generally looking down on childrearing, I think it's possible and great for someone to be ambitious about it.
Alimony is a bit amusing to consider from my perspective, then. It's being seen here and elsewhere as a bit of a "woman takes my hard-earned money" thing. I could easily think the opposite! I'm not sure all these people would necessarily appreciate being on the end of that kind of criticism if they made any sacrifices for my ambition that created an imbalance :) And with my relationship and aiming to work with my partner as much as possible for the benefit of our family, I wouldn't begrudge spousal support so easily, even if we split acrimoniously.
