Random thoughts on finances:
1. Everyone is wondering why she wanted "her" money and how she didn't think that the money she earned was "hers". The assumption here is that BC and NC were ANY sort of a team trying to dig themselves out of debt (probably because that's how you look at your own marriage) they WERE NOT a team - he made it clear that HIS money was his (removing her access) and they were looking to separate. The "allowance" was his decision, the accounts were HIS and she had little that was HERS. Since he was looking at the entire Cisco pay as "his" - why wouldn't she look at painting money as HERS? This was not an effort to live within their means, dig out of debt or control spending. This was pre-separation division of finances. And she wanted SOME control over her own destiny.
2. She does deserve some of the money he's making. And she's rightly and legally entitled to this via any separation or divorce. She went with him, supported him (at least early on) had his kids, and all the stuff that allowed a husband and father to pursue his CCIE and MBA without having to worry about changing diapers or running kids to the Dr's office. That kind of freedom that some men have IS worth something - as it allows them to focus on their careers.
And honestly - even if she was mean, spiteful, greedy (insert unflattering descriptor here) it's ok that she's dead? Or - we think Brad would have had a right to kill her? Or what - this points to other suspects? (not really - the more that folks disparage Nancy, the more it looks like they are saying they think BC did it and they don't BLAME HIM!)
Lastly - is there any information or statistics on spousal murder that would suggest how many spouses are murdered where there have been ZERO reports of physical domestic violence prior to the murder? I think this had to be quite premeditated - because as emotional as their marriage was a the end - the hating, the fighting, etc - if he had self control issues - wouldn't he have lost it prior to this and hit her? I see this as more of a cold / calculating deal than of a "lost it" scenario.
