Does this verb form strike a strange note with anyone but me?

Like here: “Has this ever happened to you? You had become more (physically) attracted to someone, the more time that had you spent with them?” All respects to jmah, who asked this question. It’s a good question. But why not “you became” and “you spent”? Why so complex? Why not also write “Had this ever happened to you?” I don’t get it.
