They seem to have been doing just fine financially. They were out playing around, eating at a place her bosses were comfortable at. Doesn’t sound as though the finances were a problem.
Since she got another man, just like the first (except he isn’t the natural daddy to the little one), that makes your point mute...doesn’t it?
The subtext of the story — in the first few paragraphs — is that the first husband didn’t suit her job.
I would guess that they weren’t “out playing around,” but at a business dinner.
Also note — you don’t get to keep the kind of job she has/had forever. You don’t get to keep it for more than a couple years, then you’re either moved up or out.
With some of these jobs it’s very tough stuff. You either have the whole package or you’re toast.
