Sometimes, we have bad news and decide to hide it from our loved ones, this makes it more disastrous when the truth is let out of the bag because not only is the news still heartbreaking, the partner feels betrayed that the news of such importance was hidden.
Communication is key and seeking of care from experts is also encouraged for any challenge.
Yes, being secretive with your partner on a critical matter such as this is dangerous in any relationship.Such a great honour to have you share your view on this matter, @graat .
