"I never loved you" because that means they were lying about loving me our entire relationship

Worst I'd say would be "I never loved you" because obviously as it says it shows that you never really meant anything to him and all he was playing was a game. However "I don't love you anymore" shows that he once loved you and all those feelings, kisses and laughs were true, but overtime they've just faded..
