I think you could take a pessimistic view on this song, but from the way it sounds to me, I choose the optimistic view.
For those of you who know the BNL song 'Break Your Heart', he considers himself a coward for never getting out of the relationship when he know he should have and then finally gets the courage to leave at the end and is very happy.
In this case, instead of leaving, he realizes that despite the problems in the relationship, he cannot turn his back on this woman. He's already where he wants to be. He is already home. Then when they are old, he wonders if she'll ever realize how close he was to leaving.
