But maybe her dad did not have much wealth for her mom to take half of.
And so what that her mom was looking for security? It could just be a rational, "business decision". Deep down her mom was probably attracted to something other than money.
He/She said his dad was wealthy. Regardless of how much it might have been, it implies he had more money than the mother at the time they got married. Which means she got half of it, or at least a portion.
Ergo the marriage increased her own wealth significantly, and now she doesn't have to care for status or wealth, and can simply bang whoever she wants based on looks, not caring about financial security.
Whether it was a rational or irrational business decison, we won't know, we just know that is what she did. We'll never know what goes on in her head, we just know her actions. And her actions were finding wealth and security.
Maybe user multiple was concieved by his/her parents out of love in a loving marriage which eventually broke down.
Maybe he was concieved as a "meal ticket" baby, for his/her mother to enjoy financial security.
We'll never know.
*(not trying to offend you multiple, just using wan's wording when it comes to women interested in money only).
