Unless we take emotional risks, there is no chance for trust. For someone to earn our trust, we have to trust them with something. That is why it is impossible for trust to be a one-sided exercise.
Of course XH will need to earn your trust, again, just like any new prospective romantic partner. And, of course you should take your time.
All I'm doing is to try to shift your perspective from what is "his work" alone, to also consider what falls into "our work" and "my work."
