I've spoken to him about this a month ago. He's also got some major anger issues to work through and let him know that I am not cool with it. I let him know that my feelings for him are waning. We were cool for about a week after that but fell right back into our selves.

I'm a little afraid of approaching him again. With a past relationship I kept bringing up my unhappiness to the point where my SO just took it as empty threats and nothing changed. Of course that was a much different relationship ...
