Ex Best friend

“Save me all your firsts, they're mine to take"
I shouldn't be in love with my best friend, I shouldn't value whatever he says at least. He left when he was thirteen without a word to me.
I tried contacting him but couldn't reach him, so I asked his mum about him.
She said he'd gone to be with his dad.
He returned five years later, no longer as my friend but a bully.
He was back for revenge but what I did, I had no idea. He hated me and wanted nothing to do with me.
I tried understanding and talking things out with him but it was obvious, he wasn't interested.
My attraction to him was still there, if possible stronger now. But I'd lost the only person who understands me most.
He does everything in his power to hurt me and make me cry.
My best friend became my bully..
