Should I call tomorrow and say I;m ready for his explanation?
NO!
That's exactly what he wants you to do and take the upper hand away from you.
Stuck hit the nail on the head, fairly soon you may very well be told YOU are the reason for his infidelity, especially if you pursue him for anything. It's nuts yes, but it's the way it goes.
Stand your ground and stand firm. Don't let his vm's or emails get to you, it's an act at the moment. Why else do you think he changed his password?
