I think many people invent little lies once in a while, but this is a little too creepy and serious, and would make me think about breaking up with him for good if he won't let it drop. Maybe delivering the ultimatum is what he needs to know you aren't the one calling (if he really is getting calls).
Why hasn't he shown you the history of the calls on his phone and where they are coming from, I wonder...
