Codependency Support Group
Codependency is defined as someone who exhibits too much, and often inappropriate, caring for another person's struggles. A codependent person may try to change, or feel shame about their most private thoughts and feelings if they conflict with the other person's struggles. If you are on a journey towards self-love, this support group is for you. Join us and find others...
As far the breaking the lease, I bet he wouldn't care if you moved out and someone else moved in... as long as he gets his rent.
I'd work on finding someone to take your place and sublet your half and then move into a complex or even rent a room from someone for the time being. Whatever brings you peace.

It's really not that hard... I think you are focusing on all the emotional dynamics and not be logical to fix the problem.
You'll get through this.
