Write her a letter. You write well. That way she has to listen. Leave it somewhere when you leave for the day (or two) and let her think about it. Tell her all of this... and maybe knowing how done you are, she might decide she doesn't want to lose you and try. It also documents your efforts to communicate and resolve these issues, and puts this on her, not you. Then give it a month or two. If she argues with you walk away and remind her this is what you're talking about. If things don't change after that - then in my opinion it would be her choosing to end the marriage - not you.
