but the OP should make the choice. i do sort of agree with what your saying, but in my opinion it's something that makes sense in your head, but just doesn't work in practice because people will take advantage when the opportunity arises for them to do so. if she isn't so demanding then he will have no reason or incentive to make any changes. that's just my opinion though. if the OP needs this information in order to make any forward progress in the trust department then he should cooperate, if he doesn't, get rid of him.
