Go man. If the woman tries to drag you into a scene(and from the sound of it, she will) walk away. If she follows you, get in front of as many peopl as possible and be polite. These kinds of people usually thrive on confrontation and drama, so it shouldn't be long until she loses her head and starts spewing venom at you.
In short, go to the funeral, if she confronts you, walk away, if she persists, drag her true colors out in front of everyone there. Shame is a powerful weapon, and acting in such a manner would draw ire against her and you would gain support from extended family and friends. If she is truly unbalanced she may need to committed herself.
