This song is about trying to get back into the swing of relationships, but failing due to becoming uninterested or turned off every time you get closer to anyone. And when it comes down to a decision, 'love it or leave it', he ends up 'hating it and leaving it'. He gets close in the second verse, but again fails by the second chorus. He tries anyway again, but pessimistically realizes that he's just going to hurt the person he's with when they feel most vulnerable. He realizes that he's getting older, and by the end of the song has lost hope in ever being right for anyone.
My interpretation:
