l2l, think I know what you mean - is he taking these steps as a way of trying to work things out with you, or is he just trying to turn you into a 'buddy', i.e. someone he can interact with in a cordial way when it suits him.

This is what I think about in regards to my own situation.
My H seems to want to continue to be my close friend, and socialise with me all the time, but he does not want to be married to me - which basically comes down to the fact that he does not want to sleep in the same bed with me overnight.
So bizarre...

And are my actions enabling the prolongation of this sort of arrangement that suits him and only him?

In your case the fact that he's talked of hope is a big positive.
I'd give anything to hear that sort of talk from my H. He just keeps saying he doesn't know, is confused, and doesn't want to give me 'false hope'.

Seems as if you're doing the right things, so hold the line and I'll be thinking of you.
