Well, he's certainly left now! What was your plan for after he left (or did you not really believe he ever would?).

We all have all those things in us (can be loving or hurtful, even to the same person!) but it sounds like being in a relationship with him now is not good for either of you. Let him do his jail time, work on his own showing up/not getting DWI's, etc. Sounds like he has to learn to care about himself before your caring will register properly.
