I've dated women who look like this. The biggest downside by far is their addiction to attention, and not just from you.
Over years, they've gotten used to getting the sexy princess treatment from every male with a pulse, and no matter how rich or good looking or a stud you are, EVENTUALLY they crave it back.
One man's no longer good enough. So they'll literally turn into an unmarried wine-aunt who gets loads of sex but zero commitment.
It’s sad when you stop seeing this as anything other than a headache and financial ruin
