If I may ask, were attorneys involved on either side in your case? I suspect that is the main differentiator between my experience and others that I have talked with that were able to settle on a sane number with their ex.
My ex-wife and I did the homemaker thing too. A lot of my peer group did. I don't think it works these days. No offense intended, but just like you never hope to be financially dependent on a man, I hope to never have a woman that is financially dependent on me again.
