This song seems to be about being with someone who you know it's right for you. You're sort of wasting your time and you realize that it's going nowhere, but you'd rather be with this person that alone ("safer in pairs", "no amount of nightmares could compare to the thought of only silence"). The relationship has gone as far as it will go ("baby, we're already there") and the speaker seems okay with that.
