“You fall in love with the person, not the gender” comes from an RPF fanfic, that then some random latin-american fansite used in a fake article. FAKE (I think of it as our very own version of the sandpaper quote)
As for “I don’t believe in labels”, the closest he said was, “We (Kurt and Blaine) are not into labels, man.” while describing Klaine’s relationship status after their kiss in “Original Song”. MISQUOTED (c) darren criss news

not blaine friendly
