Hi Reddit, I am posting here because I don't know what to do any more. 

My step brother seem's so cold towards me, He really does not treat me or my dad like a living person. Who looks at us as if we literally crawled out of hell and are the spawn of satin. 

A little back story, My dad and His mom met at work. Both of them were single although he lost his dad in a car crash 3 years before our parents got together. 

We live in a pretty big house, our parents are always away on business so it is the two of us mainly. 

Just last night I asked if he wanted to watch the spider man movie with me, he goes " I hate spider-man" This being the guy that has a framed picture of spider man in his room 

At school he saw me having trouble with my book's and did not even stop to help, I ask him for help with maths (he is a math wiz, I am not) he goes's " figure it out yourself"

I have spent the past 3 hours crying in my room, because all I have ever wanted growing up is a sibling and the next best thing hate's me. He is mean, and he has not even given me a chance. 

I want to speak to him and tell him to stop treating me this way, but I am not sure how to go about it.
