Holding secrets can be very disastrous, there are times the children aren't of the age to know some things and when the time is right, nothing should be held back from them.
Some secrets may be very heavy and cause problems in the family which can be eventually settled but allowing things to get so bad to the point of what you shared with us can be terrible.
Holding onto heavy secrets for too long can lead to problems within the family, I would suggest we consider the long-term effects and make a thoughtful decision about when and how to share important Secrets/details, before they escalate to avoid unnecessary difficulties. Thank you for reading
