Studio Arcanis

Ok first lets explain my situation, in my life I'm rounded by magicians,most of them with no morality(I'm not saying magicians don't have morality but this is the situation where I'm ), there is no logical reason for this but my life is actually this way.
Some of them like playing with happy marriages or relationships , trying to break them up or producing sexually submission of one of the partners.
So my question is , can we protect from this kind of magick? And how?
