Still not getting what OP thought she was offering with this thread. I’m not against hearing about lavish lifestyles, but OP has said nothing remarkable that’s different to other women who choose not to work. Gardening, cleaning, pets, family visits, one-off donations to charity, not extravagant holidays, kids in state school. Second home and yacht yes a bit unusual.
The £2m mortgage free home I suspect was bought a while back when prices were cheaper, and it was somewhere that needed some work which obviously DH could do. Not sure the £600k pa is actually correct in the sense of a salary, given savings are only £170k. Possibly a lot of the £600k profit is ploughed back into the business. It doesn’t sound like this is the realm of children and grand children set up for life.
You sound like you have a pleasant life that suits you OP, and you obviously are comfortably off, just not getting why you made the thread.
