Alright guys. This is not the nicest story and due to my lack of politically correct goals, this is the only place where I can ask this.

My roommate and I recently had an altercation that stemmed from him keeping inappropriate items in the shared spaces. I warned him on two different occasions. On his third time keeping it there, I told him to move it or I would. Once I moved it outside, he attempted to attack me. Cue third roommate jumping in and temporarily stopping it. Things are still heated, I do not feel safe in my house. I told him I would call the police if he attacked me again.

The bottom line is, I was crossed and now I'm seeking some help. Since I'm moving out on friday, I should avoid him and leave. But as this guy clearly seeked to end our friendship through violence. I want to get him back.

I was thinking about telling his gf about girls he's cheated on after I leave. Or telling her now, record physical reaction and call police.

My most machiavellian thought was to call a mutual friend pretending shes his gf in front of him and expose him. Once he's in a cell, he calls his girlfriend to apologize thus truly exposing himself.

I should just suck it up and leave on friday. My current anger due to the event is still fresh. I need some council.
