<human>: Can you provide a brief overview of the text?

**Note, this is slightly hypothetical as it concerns a likely, but not certain future event**

I've been dating a woman for a few years now, and will probably be the woman I spend my life with.  We've been tested in many ways and have persevered each time.  She's great, educated, and by our own merits we will live an upper middle class lifestyle and retire in our 50s.  However, being from a fairly materialistic culture, she's a bit more "expensive" than women I grew up around.  Overall, she's fairly responsible (e.g., no CC debt).

What she doesn't know, and will not know until at least we're married and I actually receive it, is that I am set to inherit a lot of money --- enough to quit our jobs and then some --- in 5-10 years.  Obviously, a lot can change in that time.  For me, it doesn't really matter either way because I like working and save most of my paycheck, but I'm worried that my wife will want to significantly change our lifestyle, e.g., move to the ultra-expensive city where she went to school.  Part of me just wants to keep it a secret forever and never have to deal with this possibility while making sure that we/our kids are set.  At the same, I want to make sure that she's happy, so for example, if she hates her high-paying job, she can feel OK quitting to go teach at a college part time, or running a non-profit.  What can I do?  Am I an asshole for thinking this way?
<bot>: Set to receive $X, where X is large.  Wife is easily tempted by lifestyle inflation, so what can I do to keep those $X productive?
