This song is a really fab song and i think most ppl will b able to relate to it at sum point in their lives. I think tht she is saying tht she fell in love with this man but now its all ova and she is hurt she is doubtin if he eva loved her in the first place. The ending i believe means tht although she is really hurting she can now see tht she in time will get ova him and find someone else and tht there is life after love and heart break.
