Lyric discussion by delial 

I think the part about "needing more than wanting", but "wanting for all time" is very clever.

I don't think it's saying he's dependent, per se. It's saying he both needs and wants her(a safer way for him to say he loves her), and he's illustrating how intense his feelings are by pointing out that if he could "want her for all time" yet also need her EVEN MORE than that, it must mean his feelings are very real, very deep. I think it's using one to emphasize the other and emphasize BOTH at the same time.

I've always felt it's pretty much the narrator attempting to be flowery and emotional, trying to get across how much he cares. I imagine the guy is very work-oriented, not very open with his feelings, and that line is his way of trying to express the vastness of his love for her. It really paints a picture in my mind. As in: "I want you for all time, see? And yet somehow I find that I also NEED you even MORE than I want you...which is overhwelming, because I never knew I could need and want a person so much."

In my mind it's one of those scenes where a person deeply loves someone but can't directly say it, due to being reserved/not knowing how to express it, so the person outlines it with lines like the ones above.

Makes the hopeless romantic in me sigh.

I think you're right but perhaps overly so. It is an utterly romantic phrasing and simultaneously a recognition of how much this person means to him. I don't think that it's written as is because the narrator can't say "I love you." I think the way he's said it is pretty (poetically) darn direct!
