I can say, “I’m over him” a million times and more

I can say, “I’m over him” a million times and more. I can stand to laugh as if there’s no tomorrow. I can perfectly curse his name. But once he’s around, I don’t know and I can’t explain. Why my heart beats so fast that I could hardly gasp, making me want to fall into his arms once again. After everything that he put me through. He still owns the biggest part of me and the sad part is that, I can do nothing about it.
