Though I see you still struggling with the way he is "pulling away more" in the last 2 months. He is pulling away because he is realizing that you are still attached and he could snap his fingers and have you back. Right now.
I think you will see him reaching out more, as he feels like you are detaching. It is CLASSIC distance-pursuit dynamic stuff. We've seen even the most wayward of spouses come sniffing around when their LBS started to REALLY detach well.
I think you'd be surprised at how much he'd reach out if you really went dark. NO messaging of any kind. Very slow, short, almost dismissing responses to his direct questions. I wouldn't doubt if he made an excuse to come by sometime if you were really to go dark on him.
The problem is that anytime he does that, you end up reattached. They key would be for you to remain detached. Stick to very good DBing rules. You are busy you are working on you, and you don't care what he says or does or is doing or is not doing. That you've emotionally moved on, and you are leaving him behind.
If you could get there, he'd feel the loss of control and he'd start reaching and acting out. We've seen 1000 times if we've seen it once. To be honest, in the vast majority of cases,when the WAS that has gone to the lengths he has (moved out, started a new R, etc), it isn't usually until the LBS is DONE with it all, and really ready to move on from their WAS, that the WAS suddenly wants to R.
