Sorry, I guess the previous post wasn't still enough.

It seems like I'm in a constant opposition with him in the session. It dissolves basically immediately after I leave and then I feel regret about the wasted time. Sometimes I write him email from the "other side". And then, when he tries to bring those things up in the session I forbid him angrily. I tell him that he is not allowed to talk about those things. Sometimes, when he tries to engage with me or suggest something to attempt to relate better, I just get up and go to toilet, sometimes in the middle of his sentence. Sometimes, I just interrupt him in the middle of a sentence saying something completely pointless. And maximum 10 minutes after my session is over all this is gone and I'm a normal thinking well-behaving person again.
