We are in a similar position here. I was also the one who ended up saying I was ready to go ahead with the D, and then setting up the mediation appt. Like you, I'm sure that my H does want a D, he just didn't want to be the one to initiate it.
His behaviour is also odd, and I would like to think that he is regretting things, but I am not letting myself go there. He and I avoid each other when he comes over for the kids; I can hardly stand to look at him. He goes around all slumped over when I'm here, but I think that's just the remnants of guilt, or it's about the kids, but not me.
He actually put a smiley in an email to me today; he has NEVER done that! Weird. I think he's just relieved that we're getting this done.
Oh well, enough about me.
Have a good day and thanks so much for all your support, N
