Everything I do he is angery with me, but he never wants to talk about what I did or how to fix anything. He bottles everything up and then throws it at me.

Being angry is a choice. A person can choose to be angry about something or can let it go (maybe after talking about it with the person whose actions he didn't like).

What does he say you do that he decides he doesn't like?

It sounds like this could blow up one day, and might even lead to physical abuse. I'd seriously give him an ultimatum. Talk or dump him.

This is a very bad sign. If you are having issues like this I think you should consider seeing a relationship therapist or maybe it is time for the two of you to take a break from each other. Sorry I hope it gets better.

How old are you?

A relationship without proper communication's not much of a relationship.

I think you need a better boyfriend.

Dump him, and let him figure it out on his own. Why bother with someone who rather throw tantrums at you rather than talk things through like an adult?
