Well I did it, and it was easier than I expected.
I could tell he was mad, but he ended up placing all his anger on the other room mate instead of me..Other room mate wasn't there, he just left cause he knew I was gonna confront blacky. Blacky told me he is glad i came to him straight forward and we could talk about it like men. Said he was mad at other room mate for coming to me instead of him. I kept telling him his antics/actions were bothering BOTH of us, yet he kept talking about the other room mate. Said he is going to confront him when he gets back home.
Great..I lay down the rule, and he is going to take his anger out on my other room mate..lawlz..
