I’m in a challenging situation and would appreciate some perspective. My child's father passed away when my son was just 10 years old. Throughout his life, my child's father believed that the man his mother claimed was his dad was actually his biological father. His mother consistently lied to him, saying that this other man was his dad and even named him after him, giving him his last name, even though she knew the truth.

Recently, my son started getting matches with cousins and uncles through an ancestry DNA test, which led me to discover the truth about his paternity. I had no idea until those DNA matches came up that the man he thought was his father was not actually his biological dad.

Once I learned the truth, I felt it was essential to tell my son right away. I don’t hold anything back from my kids, and I believe he deserves to understand his roots, even if it’s painful. Now, I’m reflecting on whether I did the right thing in revealing this information, considering the emotional weight it carries.

So, AITAH for telling my son the truth about his father's paternity, or would it have been better to keep it to myself to avoid causing him distress?
