A lot of times, song meanings can differentiate pending the interpretation of the listener. In this particular song, I don't think its a question of the relationship not moving fast enough for the other party, as in a "simplistic, literal sense" (i.e. consumation), but I do sense that the narrator is in a troubled relationship - whereas the (woman) in the lyrics has a restless heart and wants more out of the relationship/ or life, than the narrator is able to give. It seems that the narrator is very much unconditionally in love with the woman, yet for whatever reasons, the relationship is in disconnect, at least from her side - but then later he finally, begrudgingly is able to see it too (i.e. the "stumbled into view" lyric).

Just my take on it.
