I am going to concur with Andrew. I think right now CMM is fighting his own battle and may not have the physical or emotional strength for more rejection by them. Or perhaps he doesn't want them to think he needs them to care for him. I understand where you are coming from, wanting to make this happen for all of them, but I think this is going to have to be something CMM handles on his own.
I do hope he begins to feel more comfortable.
Again, you are an amazing woman to do all of this for him
