One way to test your partner's trust is to deliberately instigate a money fight. It probably will happen later if not now, and now's when there's little at stake. Figure out a few "hard lines in the sand" that an unscrupulous person would really dislike, hold those positions as far as you think you can go without destroying your relationship, then come clean once you've determined the person you are truly dealing with. People will always reveal themselves when pushed to the edge.
