With regard to “settling down”, I must point out that the only rational reason for a man to invest long-term in an intimate relationship with a woman is for the production of suitable heirs.  Anything else can be had most optimally on a short- or medium-term basis.

Of course, many men behave with an effeminate irrationality; and the whole concept of “marriage” has been destroyed, inasmuch as it has come to be based on so-called “love”, i.e. an emotional codependency of narcissists who produce children in the manner of buying fashion accessories (and then wonder why the brats grow up to be ungrateful losers).  Marriage is a reproductive relationship—not about you, not about her, not about your egos and your “love”—certainly not just about sex and good feelings, which can be obtained on an hourly rate schedule.  Indeed, if you can pay at least $500–1000/hour (the sky’s the limit), then you can hire not only sex, but also charming companionship, social poise, and even a bit of intellect.

There are some things money can’t buy—such as someone to whom to leave your money.

Otherwise, plan your liquidation phase such that hookers get all of your money before you die.  Your life will sum to zero, and you will be quickly forgotten:  Genetically forgotten, memetically forgotten, extinguished body and soul as if you had never existed.  Meanwhile, have fun! :-)

N.b. that for the aforestated purpose, you do want a beautiful woman.  Darwin can help explain why—or you may ask a dog breeder about the requirements if you want to avoid having degenerate, ugly pups.  Beauty is not skin-deep, after all; and the desire therefor is anything but shallow.
