I think that when it comes to love, this should always be reflected in behavior.

I agree, daily behavior is what really shows love, and at the same time receiving little gift this or better anyother day feels good

I think the rest has also come over from America, where people apparently make a scene if their partner forgets to buy or organize something (expensive).

Oh, yes, that's true. This day is crazy here, and any little thing is going to be expensive because as lupega says many people take the moment to make some money, for sure there are people who believe the more expensive the gift is, the greater the feeling, many are just pretending they love, and many are just taking advantage
