Similar here, Jolly. My bride was NOT raised to be financially prudent by any means. But over the years she embraced LBYM (within reason) and is very supportive of financial planning and FIRE, even as her family puzzles as to why we don't live it up more. After all, as they often say, "you have the money, don't you?" We feel we have not missed out on anything we wanted to do, and are quite content to know that yes, we do have the money. And now that I'm about to FIRE at age 57, maybe they will get it. Naw, they won't...
She and I have talked a lot about life after FIRE, that there will be some adjustments, etc., and we are both looking forward to it!
