To single out 'career women' as the ones to avoid is simply stupid, some of the best marriages I've seen are the ones between two career people.
If your spouse leaves you for someone else they met 'on the job' that's only because your relationship has been found wanting, if you think tying someone to the couch is going to make them stay you're simply wrong.
Statistically the chance of them staying may be larger, but that's a shitty way of saying 'if there is no competition I can win'. Better get your act together then.
And beware of that neighbor...
Women have been on the receiving end of their men 'trading up' for years, the equality game has its downsides, but this isn't one of them. Keep in shape, keep your woman happy and I doubt you've got much to worry about, career or not.
If you're a slob, that's a different thing of course.
