Yes frequently my sessions start like that if I have had a bad week. I struggle to be open about things, but think T can see through my "Oh yes I am fine" face. I have acually contacted an external anonymous support network this week and I even cringe when I think that T may find out about that.

But I am not sure whether you are saying that there has been issues and T has caught you with your hand in the cookie jar (like me above) - or that is just how it feels, that there is no cookie jar, but the relationship feels tense in some way or you are wary of each other?
