I think that is a necessity. I know the times in my life when I felt the most vulnerable physically, that is when I felt suicidal. I think YS needs to live away from DS. Easier said than done, I know.
I'm sorry your wife has resorted to anger. I think many people do, my SO included. In my opinion, it is "easier" for some people to feel anger than the softer, more vulnerable emotions. When angry, they feel in control and powerful. But anger is a ruse, because it can derail relationships.
Good for you for setting boundaries and giving yourself space from her; you are wise. Can you arrange lunch with a friend, too? Take care of yourself.
