Alexandra Marinina. Spring for the traps (№ 85595)

... the ability to love a man regardless of how he treats you, it is a sign of great emotional strength. People are weak inherently hostile, they know they are weak, so I try to limit the possibility of a strike on its own so initially you see all of the enemies and get closer with those who are guaranteed not to hurt them, won't offend, not to humiliate, insult. A strong man fears nothing, he knows that he will make any impact, so it can afford to love everyone. Well, maybe not love, but a nice treat. He doesn't need guarantees of otvetnoi.
