She could have a Sugar Daddy. I never cease to be amazed by how little SOME of those guys get for their money. I've seen them take young hotties to Hedonism and other resorts and then hang out alone at the bar while their gal goes off and has fun. Some are seriously cuckolded. Others get a good bang for their buck, pun intended I guess lol.
Experiences vary.
I'll speak from personal and close acquaintances experiences, I'm sure it
does not apply to all but it does to those who were described.
This person at some level really hate himself. He probably spent most of his younger life studying or working and mainly masturbating to a college/work crush who is barely average looking yet did not have the guts to even talk to her.
Now he has a ton of money, more than he knows what to do with, he finds online these bimbos that make his old crush look like crap and these are available in exchange for some gold and trips in designer clothes and private jets.
What he does at the bar is mentally mocking that crush who is now old and he is hanging with a girl that is young enough to be her daughter and way hotter than she ever was.
But, in reality, he is a sad and depressed person who knows the truth.
