I'm sorry this is happening, JDNA. I think you should talk to him about it. It may be that trust/mistrust isn't the only way to conceptualize this. Maybe another way to think about it is that he really cares - cares enough to ask twice.
I think we become very accustomed to saying things are fine when they aren't - it doesn't necessarily have to do with voices or past 'deceit.' And so your T could be asking twice for reasons that have nothing to do with voices, deceit, or trust.
