I think this songs about shes in a relationship with someone & they break up and she takes it very hard and even though the break up is leaving her sad and she wants to forget that she ever loved him because she doesn't want to be a "broken hearted girl". Also I think he hurt her so bad that she hates him but deep down she knows thats not true, and no matter what if he needs her, she'll always be there for him. & I think maybe once she finally feels free of him and doesn't feel sad anymore, then he comes back into her life and all the feelings come back again.
