Now I have the rest of the night to sit and stew if I did this right.
I think you did just fine. We all start some where. Don't stew on it. Keep it up. Trust me, it gets easier.
As far as your H not liking notes, my opinion, leave a note. He wants out, you have to do what's best for you. So if that means no direct communication, so be it.
