I know I'm not preaching what I practice here but I haven't talked to him about it because part of me doesn't want him to stop being open with me (that's the naughty part of me that enjoys feeling closer to him, not the sensible, levelheaded part that worries about its impact on the effectiveness of therapy)
At the moment therapy is going so well and I am working through some serious issues, so I kind of feel it's better to let it slide than risk jeopardising the relationship.. I think if it was affecting therapy to the point where I was thinking about quitting, I would have to talk to him about it. It definitely wouldn't be good to quit without talking it through.
