If it was a spontaneous gesture, I would say just buy a bunch of flowers, and they don't have to be expensive.
I swerve Valentines as I don't like packed restaurants, or being ripped-off by the florist.

Birthday's are a tad different, because she will want to show the gift to her friends and family. Restaurants and Spa's might be tricky with the changing Covid regulations.
And if buying jewelry , you have to be sure it will be something she really likes.
Perfume is always a winner, if you know what she likes

I disengage, I turn the page.

Shame only 6 people at a time will be able to see the lavish gift

joking aside / no dildo presents etc..
Arrange to go to a nice bar & pretend youre not together.
She goes in first, you (enters stage left..) a few mins later & get a drink, attempt to chat her up fresh.
Few drinks, maybe a meal and its a happy ending a few hours later with you podgering her senseless back home
(or somewhere iffy with her panties round her ankles)
what can go wrong?

Kids,tired of being bothered by your pesky parents?
Then leave home, get a job & pay your own bills, while you still know everything.

are you insinuating because the lady is Jewish, she is tighter than a gnats chuff ?

or a 'cash for gash' scenario ?

Jewelry is best bought together.

Cook her an uncomplicated but scrumptious meal at home.
Then scented oils and a massage from your good self
Why not throw in some crotchless panties and a peek-a-boo bra ? Everyone's a winner

I actually got a semi reading this
