Like the song says, breaking up is hard to do! Don't nurse him, he does not need you to say yet again you understand...it may come across as condescending as though he's the one who's lacking and you are the understanding care giver. I'd say yet again, don't send it but you know your sitch and the guy better than I do. And yes, it is good to write what you feel and need to say...but for you. Now you've done it Feeling for ya!
