Esther Perel is a renowned relationship expert who has worked with hundreds of couples around the world.
After advising a countless number of them, Perel says a successful relationship can basically be boiled down to one key factor: trust.
"In the age of transparency, trust has become the most important element in a relationship," Perel told Business Insider. "Trust is also our ability to live with what we will never know. Fundamentally, there is something about trust that is a leap of faith."
She added that it's important to take the leap of faith.
"If we have to know everything, if we are constantly checking, if we are constantly on the lookout, then probably we'd never trust," Perel said. "So there is a moment of suspension, that is part of this thing called trust, which is why it is so fearful and so vulnerable to trust."
