I think it's great that he's going to talk to a pastor. Who knows if he'll stick with it if he couldn't do the counseling, but at least he's making some sort of effort.
His comment about "I'm getting better" perhaps comes from the fact you are "separated" right now. Maybe he's really starting to think that he may lose you and what that means.
It may not be the solution you're hoping for but it seems most WAS just can't make that decision easily (to stay or go) -- it's part of the fog that they're in.
