It is not. Your desire to try to trigger his impulse to take care of you is understandable, but honey, he is not capable of taking care of himself. Also you don't need him to take care of you. You've been doing that the whole time you've been with him, you just haven't realized it. We are always stronger than we think we are, but it is a big step to trust in that. Take your time, focus as much as possible on you and as little as possible on him and you will get there.
