I was just thinking the harder the two of you push the more you both resist, I'll second John and say whatever you are both doing isn't working. My advise right now would be to back off, possibly go dark but I think that would make H just retreat into his shell so that not gonna work.
My gut feel K is that you are up against 2 forces, OP whether she be in the background or just in H head and H's job which I think is used as a smoke screen or barrier to avoid over exposure to you.
I know you are working to an 8 week program but at this rate I think your are heading for a D and I don't think H is working overly hard to avoid that.
Your sitch is so hard to read (understand) but if I take my far off view I think your are best focusing on Maria for a while (I'm sorry if that sounded like a cliche).
