I dated a woman who earned ten times what I did. She paid for almost everything, with me making a token gesture here and there.
I was 25 she was 39. I made up for the difference in earnings in others ways, primarily by giving her plenty of great sex and by being charming and funny.
It didn’t last and I was genuinely heartbroken, as she was lovely and I would have been with her if she was poor as a church mouse. In the end it was the age difference that got in the way and not the money.
How would I play it in your situation? Give her the best sex she has ever had, but mention you are broke and see what happens. This will include getting hold of some viagra and brushing up on how to please women.
Don’t underestimate how far being the best partner she has ever had can go.
Realistically though it doesn’t sound promising as she sounds like a princess and if so you are flogging a dead horse no matter how good in bed you are.
