You say that it's over But i'm not convinced cos when she comes over you're always hiding it you say she's a cool girl and we'd really get along but when we're together I don't belong now you've been talking in your sleep and now my head's all full of these insecurities as we call a cab to leave I turn and I ask you again Is she gonna be there? Cos I know what you said but baby you've got history tell me is she gonna be there is it all in my head cos I can see your chemistry I'm trying be cool but baby you're making me crazy I'm trying to be cool by saying that it doesn't phase me but if she's gonna be there you can go, by yourself cos I'm gonna be somewhere else I'm not a ***** I don't want to keep you home But it's making me sick If you're going on your own I see you light up whenever she arrives and you hold on too long when you're saying goodbye now you've been talking in your sleep and now my head's all full of these insecurities as we call a cab to leave I turn and I ask you again Is she gonna be there? Cos I know what you said but baby you've got history tell me is she gonna be there is it all in my head cos I can see your chemistry I'm trying be cool but baby you're making me crazy I'm trying to be cool by saying that it doesn't phase me but if she's gonna be there you can go, by yourself cos I'm gonna be somewhere else and I know you think I'm jealous But I know that she wants something else and I know, but I can't help imaging things every time that you mention her name Is she gonna be there? Cos I know what you said but baby you've got history tell me is she gonna be there is it all in my head cos I can see your chemistry I'm trying be cool but baby you're making me crazy I'm trying to be cool by saying that it doesn't phase me but if she's gonna be there you can go, by yourself cos I'm gonna be somewhere else
