i think that this song is not only about communication problems, but specifically talking about the ending phase of a relationship..that it feels empty. when he say "there is no lonlier place/than lying in this bed" he is saying that basically the relationship has just amounted to meaningless sex. the "chemicals" is basically all that there is left in the relationship..no real love anymore. it's pretty sad.
