this song is about jealousy and paranoia. it doesn't have to mean that the girl is actually unfaithful... i think he's trying to reason with the fact that jealousy is destroying the love. i think "you're so pretty in white. pretty when you're faithful." is him reassuring himself how good it is when he isn't plagued by jealous worries. he's trying to combat his jealous nature.
so i think inflatable means like a floatie. a lifesaver. they both were falling apart, but his love for her makes a lifesaver, for the both of them. hope will keep him afloat.
