I'm sorry to read the recent updates in your thread -- I had hopes for your sitch. However, I am proud (if that's the right word to use) that you are traveled your path and know the way you want to take.
I agree with Wonka, is there a place where you can go and gain perspective? Or at least go, once you announce your desires for a Divorce? I think space would be beneficial for you both after you talk to your H. I couldn't imagine having to have lived with my H with his spew and after he announced his intentions for us to D.
I'm not trying to discount your feelings at all, but I do advise you to proceed with caution, especially with a history of violence and with suspected mental illness. What I've learned from my own mentally ill father and my (suspected) mentally ill h, you never know what will be the thing that sends them over the edge. Never in a million years did I think my H would do the things that he's done, but something in him snapped and he became a person that we don't recognize. While you aren't in fear and don't feel unsafe, never discount that a situation has the potential to become unsafe or escalate further than it already has. Or that you could ever imagine it could be.
Just my words.
Good luck.
