Its good he is honest, but maybe he still feels that there is something missing or lacking in your relationship. Of course you could not help but feel disappointed, but I hope you were not too rough with him (you said pushed him away), as this may start the cycle of lying and hiding again, with the justification that it will just hurt you. Detachment, low expectations should still be your mantra at this point. They help pave the road home for his heart (since he has never left).
If you look at the stages, truly, they do overlap and during recovery, the MLC'er goes back and forth as well.
Since my H is also seeming on the way out of the tunnel, I also tell myself not to expect too much; steel myself to not react if he backslides, and just keep my fingers crossed that I could do what I say ; )
