I will definitely continue trying! I figure if he's up to something, he's going to slip sooner or later. I will say a lot of his suspicious behavior has stopped. He doesn't act defensive anymore either. He's not totally open - not leaving the cellphone around the house - but if I ask about something casually I don't get the angry/defensive response I was getting a month ago. Doesn't mean I'll let me guard down - just taking note.
