Thank you all for your thoughts and input. It's amazing how much wisdom I get from al-anon and all of you. My gut was telling me this letter was a bad idea, and you all pretty much confirmed that. I need to find the courage to take action to take care of ME. And that means there is nothing wrong with my exit plan, and I don't need to continue to beg him to change. I wish my circumstances were different, and I could leave sooner, but it looks like I will be stuck in this home until the lease is up in May. But in the grand scheme of things, 6 more months will be ok. I can live with that. Thanks again for all the wisdom.
