Corporate Holiday or Real Holiday?

So the story goes:

"Saint Valentine's Day (commonly shortened to Valentine's Day) is an annual holiday held on February 14 celebrating love and affection between intimate companions. The holiday is named after one or more early Christian martyrs named Valentine and was established by Pope Gelasius I in 496 AD. It is traditionally a day on which lovers express their love for each other by presenting flowers, offering confectionery, and sending greeting cards (known as "valentines"). The holiday first became associated with romantic love in the circle of Geoffrey Chaucer in the High Middle Ages, when the tradition of courtly love flourished." (Wikipedia)

But my question is, why?

Why did Pope Gelasius I establish this day? I understand that he probably wanted a day for lovers to express their love, however, it seems Pope Gelasius didn't have a very keen insight to romance and relationships. Now, I'm not saying I know anything about Pope Gelasius and his relationships, because I've never even heard of him. I could do further research but it's not my point really, so it doesn't matter.

My point:
Lovers should celebrate their love every day, not just one day out of the year.

So I question, why did Pope Gelasius deem Feb. 14th Valentine's day when in reality, for two people in love, everyday should be "Valentine's day".

My next thought is, maybe the Pope wanted to establish this day as the 'focal' point to relationships, if you will. Like Christmas, we celebrate the birth of Christ, but Christians should praise God everyday. I certainly hope that is what Pope Gelasius was going for.

But why has Valentine's Day turned into a huge chocolate factory, card giving, flower sending shoebox decorating holiday? Where did this mess come from?

Why do we spend $13.5 billion on chocolate and cocoa products for Valentine's Day?
Or $422 million on Flowers?

I don't understand why people would spend so much money all for one day because someone said so. Doesn't it kind of show conformity and almost fascism?

I know everyone reading this is probably saying to themselves right about now: "Wow this girl is pathetic, she's only pissed off because she either got dumped last Valentine's Day or doesn't even have a man." Well it's actually the opposite, I had a great boyfriend last Valentine's Day that yes, bought me flowers, and this Valentine's Day I do have someone. But I specifically asked him not to do anything for me or get me anything because if he ever felt the need to express how he felt about me, or just wanted to buy me flowers for no reason at all, the last day of the 365 days in this year would be on Valentine's Day. If a man really loved me as much as he acts/says/ or even really does, he shouldn't need a national holiday to tell me.

But then again, I'm never opposed to getting flowers or chocolate on any random day of the year, even if that day randomly is February 13th.
