Lol no need to create a whole new story, mate. I agree with her. Valentine’s day is not an event where you HAVE to give something materialistic but rather that gift giving is a representation of giving love which what the event is all about. She would have appreciated it even if you probably just gave her a handwritten letter and maybe cooked for her. Those things don’t cost a lot but it is thoughtful and caring. Giving cold cash feels like you are just throwing the money at her. If you really wanted to help her with money then just give it someday else not on valentine’s.
Correct. Actually, from Op's story, it's not about financial insensitivity, it's just that men are less sensitive to big days or you could say the moment is not right. On Valentine's Day, of course women expect something different to look romantic, and of course small gifts such as flowers will make them feel loved and appreciated. If you want to give money or teach a woman about finances, you can do it the next day.
In my country, even men are demanding during valentine’s. They are even asking to be gifted motorcycles, shoes, and accessories. It all depends on what kind of relationship you have with your partner and what you expect from each other.
I think almost all countries are like this, on Valentine's Day giving gifts to your partner has become a necessity, it doesn't need to be expensive, the important thing is that he is impressed with our gift. I myself often give gifts and money to my partner on Valentine's Day.
