To me, it sounds like he's detached quite a bit and yes, generally once the ball starts rolling on divorce, they follow through. In their minds they have do this no matter if it's the biggest mistake of their lives. Of course, when they say that they will always be there for you, they are hoping to be friends, but also thinking that you will be right where he left you, if he should ever wake up. Unfortunately, time doesn't stand still and we all have to move on and do the things that we need to do for ourselves and in some cases, we do meet new people and begin again.
I know you've been trying to figure him out...you can't. He's operating on pure emotions and isn't thinking rationally, nor will he listen to any rational talks. Yes, it may appear to be listening, but in many cases, they will continue on their destructive paths.
However, please remember...if he should wake up and come to you, you ultimately will be the one to determine whether to reconcile or continue moving forward.
I am very sorry that you are having to go through this.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
