Been wanting a divorce for YEARS but truthfully afraid of my wife. She can have bouts of physical anger (not hurting anyone, but throwing and breaking things) and screams.

We have zero in common, conversations are always one sided, no sex, no intimacy and no attraction, not even a real friendship. Let's face it, I'm more friends with the grocery check out person than I am with her... I've felt dead for so long and want to be free to live life.
Also concerned about her financial well-being as she does not work.

But how to start with one so quick to anger and aggressiveness?
