Honey money phase probably wore off a bit for him, and its back to business as usual..aka me 1st! 
You should call him out on it, because if this is a problem for you now its only gonna get worse.
But yeah, he's probably just transitioning out of the HMP.
I know I did the same thing at one point in my life, the sucky thing is I had people from all walks of my life tell me I was screwing up. I couldn't see it though, didn't see it until after the relationship was long over.
I was so bad with this
I was like the best worst boyfriend at that point in my life.
You live and you learn tho
