My advice is for you to do what you are doing. It looks like its giving him some motivation to grow up a bit.
This doesn't have to mean reconcilliation. He really needs to have that growth period before you would want to do that anyways. DBing is a way to trigger that growth.
My guess is your actions are actually waking him up a bit. I would just keep at it. There's nothing here that indicates you are pushing him away from you, and eveyrthing to indicate he's feeling closer now...so why would you change your approach to something else at this point?
