I still haven't told him about the phone records or IM log that I have.

I just don't know what to do. What are appropriate boundaries while separated?


WHAT ARE YOU WAITING FOR??? Tell him.

Are you already separated? If so, you have no legal right to check on anything not in your name. If he has chosen to leave and be separated, you must respect his right to do so. Hopefully he will return to his family... but right now.. work on keeping you and your daughter mentally healthy.
