LOST: undecided title

A love lost, it's time to let go.  I thought I knew what was coming but I guess I didn't know.  I wanted to prove him wrong and make him see that when I left I wouldn't be forgetting.  I wanted to stay with him but I guess I'm naive and now I'm not sure what to believe.  I thought I was going to love you forever, but now that we're not together, he doesn't act the same and I don't know what's happening and I don't know who to blame.  All the times we could've shared are gone so now all we can do is move on.
