The Script - For the First Time Lyrics Meaning

I believe that this song is about a couple who loved each other dearly, then grew apart, while the guy spent his nights drinking his problems away, the girl was working hard at home. Then, one day, her heart condition acts up, and he's not there for her. He comes, she gets treated, but she can no longer work. He then gets fired from his job. He tries to make things work, tries to help the girl, and be there for her, and he finally stays home with her and they feel like they meet for the first time.
