I should think you are in shock.
When you can get peaceful enough to hear your own inner self, review the possibilities, and you'll find it easy to rule some out immediately, they'll feel not quite right. I expect you'll find you do know what to do. But if you aren't sure, just do something, I mean anything - very soon you'll get a sense it's not what you should have chosen - or a sense that it is.
You're the best person to ask, you see. Better than handing the decision to us lot
or to an instruction book or anywhere else. Something will make you feel comfortable, comforted, and "ok".
One part of the Devil's message is about control... this guy surely is a control freak to some degree... just a thought.
Many people who know nothing about tarot think there's a connection with black magic, or something anti-Christian. He may have been wary of the cards in that way. But the fact he did this in temper says his intention wasn't to protect you (however misguided) but to exert his own power and enforce his own rules.
It wasn't his place to take the decision out of your hands. And force never changes anyone's mind anyway.
