Confusing Romance

"We've known each other for so long! Why would you turn against me?"
"Because I love her!"
"Is that your answer for everything you do?!"
"Your just jealous of her so f* off!"
"Jealous?! Are you serious right now?"
"Heck yeah! I had fist fights with you, and you had fist fights with me plenty of times! I don't even argue verbally with her! Just give up trying to be my friend any longer."

You have a boy best friend. You have known each other for more than three years. Your boy best friend starts flirting with you as usual. You softly push him and at the same time on purpose to see if the rumors around school was true, you roll up his sleeve and you see a multitude of cuts on his arm and a vampire bite. You were very shocked and disappointed that he would do such a thing. He notices you saw the cuts and bites from Hannah. You know for a fact you could get killed from not telling anyone about a vampire. He threatens you to tell no one or he will tell your huge secret. You push him against the wall to run and tell someone and he harshly pins you against a wall. This is no average fight. A normal fight between you two would've led up to violence, but never start with it. He leans into your face closely and whispers in your ear, "you'll be next if you tell, but then again I can't trust you, Can I?" Then with ease, makes a sharp and deep bite in your arm and leaves you crying in an alley.
