Artist I can definately see that he pulls at your heart strings and I hope and pray that his words are genuine for your sake. I am sure you are all the things he said you are in his letter. He is right the work he needs to do is his alone to do. Its his choice and his job to do it. If he doesn't want to lose himself or lose you then he will. Just as its his choice to do the work its your choice what you can handle and what you will live with. He has choices and decisions to make and so do you. He can turn this around if he wants too. HE can do it.. Hold on to how that letter makes you feel and tr to feel that way about yourself. Love yourself and maybe him enough to take care of you. I believe you will do what is best for you when you are ready to make those decisions whatever they might be.
