Wonka has given you some good advice. If and when you are feeling happier and more whole as a person then decide if you want to legally file. It is better to make life changing decisions when you are in a logical mind frame frather than reacting in an emotional one.
I continue to think that HP's posts have OOZED "logical," as well as wise and even-handed. Sorry, I'm just not seeing what others are seeing?
Now, whether or not he's been in this frame of mind now LONG enough, to make such a permanent decision? Only HP knows that for sure. But even FILING for D doesn't have to mean that's where his story will end, as my own sitch (and others) will testify.
