I believe this is the song of a woman suffering from depression because of lost loved one. She says, "I don't like walking around this old and empty house", which may mean that she is lonely and the house they once shared seems empty and old without him there. Next the man says, "So hold my hand I'll walk with you my dear", which may mean that she is hallucinating that he is there to comfort her. Next she says, "The stairs creak as you sleep, its keeping me awake" and the man says, "It is the house telling you to close your eyes". This makes me think that maybe the woman is becoming suicidal and the man is trying to lure her to her death (to him). What better line is there to support this than the next? "And somedays I can't even trust myself/its killing me to see you this way". She cannot trust herself to stay alive, And the man wants her to end her life so that she can be happy. "There's an old voice in my head that's holding me back" may refer to her conscience telling her that she can still be happy if she lives. The man says, "well tell her I miss our little talks", which might mean that her conscience us her when her lover was still alive, which would explain how the lover said he misses their little talks. "Soon it will be over and buried with our past/We used to play outside when we were young and full of life and full of love", is the man saying, 'when you die the pain will be over and we will be together' and the woman is saying that things have changed since you died and we grew up.
