Disclosing your seed phrase to your love one’s family, wife, relative etc is not the problem, the problem is who should you trust with such information. I see nothing wrong telling someone you trust about your seed phrase definitely one person is enough probably if something happens the person should be able to provide the details else you’ve lost your coins forever. I know we’ve all read different types of story about such situation, most of the stories are related to disappointment and regret still everyone with their different personalities likewise their family, if lacking any trusted person to share such personal details then it’s better you keep your seed phrase to yourself so you don’t get robbed.
