You know, my husband did not tell me the *whole* truth about a couple situations I had asked him about. Then the real truth came out later.... but it did come out, the full truth of the matter. I think the fact that he did tell you the full truth can tell you something important. Yes, he wasn't fully upfront when you needed him to be, but then he was upfront eventually. So you now know the full truth, and he's not hiding it from you. It's understandable, his fear of losing you and why he wasn't fully upfront, if it was so bad. I think you can just be honest, tell him exactly how that made you feel, and ask him again to always be fully upfront with you. I do trust my husband, who has promised the same to me.
