The universe has done you a favor. I am not being callous. I know your broken heart is very difficult to deal with and you are hurt and sad and bewildered. But (and this is a big one) the relationship you had was bad for you. And you could not walk away from it. Now you are out of harm's way. Hope that this person can get help for himself and be healthier and do well. Just do it from afar. I wish you well.
