If it's real magic, pretending it's not real will do precisely nothing other than enhance the shock of realisation when how the universe actually works becomes all too apparent... "Magic isn't real" they repeated as the car drove into a ravine.
The good news is... it is overwhelmingly likely that this is not real magic. Real magicians generally aren't in the habit of telling their victims when things are about to go south. By the time someone has gained that level of insight and power, they're very unlikely to use it impulsively and destruction is only a necessary evil after all other options have failed. A surprising number of non-magicians do use the threat of magic which is interesting. All these years later and humans seem to know there's "something there" sufficient that they'll turn to it as a last resort.
If it would make you feel better, scatter some salt or Holy Water around your house and say some prayers. You could even do an LBRP.
If it is real and you want to retaliate, use the "Gingerbread Man" ritual from LaVey's Satanic Witch. I can recommend that personally but don't use it without due consideration of how you feel and without full awareness that things can manifest in stronger-than-intended ways. The last time I used it, years ago, was after a series of difficulties kept occurring and, when they did, a person's face kept flashing before my mind's eye. This added up until life felt like wading uphill through wet concrete. I divined that this wasn't just a usual run of bad luck but that something magical had been attempted and, through friends of friends, it came back to me that this was in fact true. Someone I used to know had cursed me. I used LaVey's ritual and, three weeks later, she died in a freak accident, failing from a bridge. She was 41. At the time, I was more interested in "returning with interest" than being fixed to a particular outcome. Had I known it was going to have ended the way it did I might have rethought but, hey, she rolled the dice...
