I personally see it as a realization of the harsh realities of long-distance relationships, and the perils of dating a touring musician. Yet within the song, it seems as if the author's problem with the relationship isn't the distance or strain, it lies with the almost overcompensation on the partner's hand. He isn't that hard to impress, he says, so really he seems to enjoy her company. Hell, he might even love her. All she has to do is not try so hard, but that'd be asking her to tone down her love, which he simply cannot bring himself to do.
