Anonymous school confession

During the uni days, I had a teaching assistant living next to me. One day I have found him crying in front of his door. I approached him and asked him what is wrong? He explained that his partner left him. I stayed there to support the guy and talk to him. During the conversation I also found out he's gay. We became friendly afterwards. Some time later he tried to make me his rebound guy (I'm straight as an arrow, which I explained, but he wouldn't believe me). Anyways I used his advances as a personal entertainment and I was making fun of him. Later he entered my room while I was sleeping and tried humping me, I woke and beat the shit out of him.
