All this stuff sounds blow-your-mind romantic but it really doesn't take that much to make a woman satisfied on valentine's day.
Not me anyway, but then again I'm simple.
For me a handpicked flower, a nice dinner (salad, entree, maybe a slice of cheesecake for dessert), a hot bubble bath afterwards would definitely be heaven. Of course the kids would need to be elsewhere so you could have some nice music playing and not be screaming for them to eat their dinner.
But even the entree doesn't have to be fancy - I'd rather have something simple that tastes good than something that's gonna stress him out cooking it if it doesn't come out perfect.
V-day shouldn't be about pressure, it should be about spending some time together and taking a break from all the bullshit in the world for a while.
