Ok, glad I could make you laugh. To be slightly more serious...
I take that back. I think he MIGHT know what he wants. He sounds like he may want a new life with you, one that does not include the yelling and other negative behavior he associates with the "old" R. He wants that but is in no way sure he can ever have it.
I say that because for someone who doesn't want you around, or to be around you, he sure is calling, texting and showing up a lot. I think ANYTHING that even looks like the past to him is scaring the hell out of him. Now, he even has medical reasons to fear the "old" life you two had. He is somehow convinced that not only would it make him unhappy again, but kill him too. I guess he wants to die with a smile on his face...sorry...morbid...my bad.
Anyway, I think there is something still going on with him but it's not really up to you to figure it out. I also agree with a lot of other people that it's not up to you to plan his life for him, or really alter YOUR life to suit his needs. You know that though.
I can't wait to see what he said when he showed up at 3am...
