Mary - you can't do anything about what already happened so focus on tomorrow and no matter what his attorney says, don't react in any way. I doubt what happened at the last hearing will have any bearing on what happens tomorrow but if you keep reacting it is likely to hurt you.
Additionally, how your husband came to be in possession of those journal entries isn't really going to matter in the end because it is so far beyond the scope of the hearing. But if you were told to write your feelings as a form of therapy and you have a letter stating as much, yes, that should be of some help to your case. The judge is going to want facts. Is your daughter fed? Is she bathed and clothed, attending school, are you an involved mother (such as at school)? Those are the things that are going to matter. Not the spin your butthead husband tries to put on them. He and his motives will be flushed out soon enough because this ain't that judge's first rodeo. He sees this kind of crap weekly at the very least.
