Aouch! The fit of rage and the broken foot are a fitting metaphor for how we mostly hurt ourselves with our rage. I'm really sorry for you. You had enough to deal with already.
A quick tip for dealing with your W: STFU. I wonder why we didn't think of that before. ;-) But seriously, after you've made your point, don't try to have the last word. You say: "I'll talk to my solicitor" and whatever she replies, shut up. It means you haven't changed your mind. And it makes you look strong.
Also, try to speak more with your actions, less with your words. You often tell her what are your intentions, your feelings, your future actions, etc. Take it that she'll never believe you because that's exactly what happening. Has she ever said "Oh, you're not trying to get in the way? Sorry, I misunderstood"? No. Yet, you go back to this over and over. Ignore all of this, even when she brings it up, and act, period.
Again, really sorry about your situation. Remember: "Comedy = Tragedy + time" so perhaps one day we'll all have a different perspective on these difficult times... I know I've already started joking about my sitch with some friends, a sign that I'm getting better.
