I love this meta. I love your picspams. You just generally rock. xD
Aw, shucks...

whether the non-slashers like it or not, their "emotional affair," as you put it, is canon.
That's what I think, too. It's just there. Now, an eventual/current physical affair and various details may be from our fevered slasher imaginations, but I thought after Bonnie showed up, TPTB were really emphasizing their odd relationship. (It seriously shocked me when I read spoilers for that ep.)

Also; is that spoiler really true? Haven't heard that one yet.
It was mentioned right before S4 started, and hasn't been mentioned again for a while, so I was beginning to think I imagined it, but .
