If you are talking about a long term loving relationship leading up to marriage I would have to say no because trust is one of the most important things in any long term relationship and without trust it is inevitably doomed to fail in the long run. My Wife is the one person next to my sister I trust the most in this world and I am the one person she trusts the most in the world too and I honestly don’t see a relationship functioning without that because if you can’t trust your partner, who can you trust?
