I don't know but I think it was planned from the very start when the characters were being created. Even if you ignore Spike's crush on Rarity which is canon since the first episode you get a bunch of weird things about them...

1) Out of the six ponies, Rarity became the element of Generosity. It could have easily been any pony except for Twilight because she's the main protagonist.

2) Later it was revealed Spike has to fight the urge of falling into greed because dragons are cursed to be greedy by nature. Otherwise, he'll turn into a real dragon and destroy everything.

3) Rarity's talents, magic and cutie mark revolve around gemstones. She appreciates gemstones for their beauty and can locate them with her magic.

4) What are the chances of Spike being a dragon that appreciates gemstones for their taste. He appears to be an expert when it comes to gemstones because he can obtain really rare ones like the Fire Ruby and even manipulate them by "aging" them (however the heck that works.)

All that stuff was revealed over the course of an entire season and a half. Its like the writers are developing Spike and Rarity by giving them various reasons to be closer one way or another even without using the "crush" plot device. I think its too many and too convenient to be coincidence.
