Ah, not that part. The sending you his musings when he can't really (and may doesn't want to) talk about them in any kind of productive way with you and without any kind of timeline or anything that might get you some closure on things. It seems like it meets a lot of his needs and zero of yours and could imply, "wait for me, but don't have any expectations of me." which is not ideal in a friend or a lover.
