Funny to see this here again. I've had a bad time as well.
Tried counselling, which of course is not recommended, out of desperation. This is someone I need to get on with on a functional level.
It didn't work because he spent his time trying to show what a rubbish person I am, while I tried to get him to see that I have tried everything I can to establish an agenda around looking after our shared responsibilities.
So he would say: Imbroglio doesn't tell me anything!
Me: well, for example, I emailed you about X five times and you didn't reply, so in the end I had to deal with it on my own.
Him: You haven't given me any information about Y, which you HAVE to.
Me: I put a whole pack of papers about Y through your door two weeks ago, which you haven't acknowledged.
Him: You won't discuss Z!
Me: We had independent advice about Z, which I arranged, and the advice was not to go for that option. I said if you weren't happy you could seek a second opinion, but you haven't.
Him:You don't involve me!
Me: [Leaves room in tears].
He was furious when I stopped the sessions.
