Well, I usually assume that when the playing field changes without notifying me then I change game plans. If he does it and it is something to worry about, when you do it will come to light. Start having a friend whose number he does not know text you in the morning and act the same way he does about it. See what happens. Be ready for a blow out though because chances are it will happen. I have tried the confront method and it never works. So I just show them through the same actions what they are doing and it gets their attention. Like I said though be prepared for a possible blow out, the truth will probably come out when the blow out happens but it is usually not a pleasant experience getting there. Men are hard to see what you are talking about but when you show them what you are talking about without words, it usually works like a charm. Good luck

Ask him if you could have his phone for one day...let you answer his calls and take messages for him. If he says no, there is your answer.
