A young man with a dark past is trying everything to stay sane until the love of his life becomes unfaithful, he turns to the voices inside, can he quiet them or will the voices drive him to kill.

As Richiev said. ?He comes across, as a pathetic, passive victim of circumstances, first of the girl who dumped him, then the voices inside his head. ?The protagonist should be driving the story, but in this case, the story seems to be driving him..

I am not seeing any reason for the audience to connect with the lead character.

Also, you don't need the first part of the ?logline.
