Back in March, he lost his first sponsee and proceeded to withdraw from me, entirely.
As a recovering alcoholic (24 years) I've also lost sponsees. I felt sad, yes, but it never affected my relationships with other people. Sounds like a convenient excuse. And, it sounds like this relationship isn't rewarding for you and that's what I'd focus on. I recommend Alanon, where I learned I'm powerless over people, places and things. We can only change ourselves. Good luck!
