Johnny Depp, if you're reading this, Will you be my utmost Valentine? Dump that French bitch and BE MINE.

Living in the near-shadow of a certain circa-1950's St. Valentine's Church I wonder about this saint. O patron saint of crazed BINGO players, bad car parkers (see aforementioned) and modest stained glass windows?
No.
Valentine was one, maybe two, different people. One was martyred in or around 273 and the saintly guidebook states that both accounts of these guys "are equally unreliable." Then Chaucer of all people gets involved, although they don't mention in which part of his oeuvre mention of Valentine happens but then that gets all screwed up as Chaucer might have been talking about when birds mate mid-February, or maybe a royal hooking-up. Or it might be some remnants of the Pagan Lupercalia festival.
Anyhow, Valentine is an all-purpose saint:
beekeepers, travellers, youth, epileptics, fainters, victims of the plague and lovers can call invoke him for their very private physical reasons.
