I got the strong feeling that his first decision for separation was really a ploy, where you were supposed to break down, grovel a bit, and beg him not to leave you.
OK, so you didn't behave as he scripted for you, and now he is into "get my enabler back" mode, where he is the crying, upset and grovelling soul who needs you so much.
As the others have posted, it is quacking and means nothing more than any other duck quacking. His actions and behavior is what speaks truly, and even that needs
watching for long enough to see whether it is fair dinkum change or just another role he acts in his play.
