Knowing when it's over

It's when you don't accept my calls and you no longer write
It's when every time we talk it turns into a fight
It's when you said so many things that were a lie
It's when those hurtful deceits would make me cry
It's when I was locked up and you were out doing your dirt
It's when you never cared who you hurt
It's when another gurl is in my dreams
It's when everything I said I no longer mean
It's when I can't believe a word you say
It's when no matter how close you are you seem far away
It's when I need you and you're not there
It's when you don't seem like you even care
It's when the words I say no longer flow
When it's finally over this is how I'll know
