Ten months after a man’s wife passed away, he finally got the courage to read a letter she left him, which contained a devastating admission. The son they had together may not be his. “My ‘darling’ wife passed away 10 months ago,” the man wrote on Reddit’s Off My Chest forum. “She wrote a letter for me before she died, but I couldn’t bring myself to read it until now. She told me how sorry she was that she didn’t have the guts to tell me this to my face when she was alive.” A letter that changed everything In the letter, the wife revealed that there was a “good chance” that the son he thought was his wasn’t his biological child. A few weeks before their wedding day, the wife got drunk at her bachelorette party and had a one-night stand with another man. Soon after that night, she became pregnant but was unsure who the father was. A man reads a lettter. Photo credit: Canva  The man was torn whether or not to have the paternity test done. The child had only one parent in this world, and he would have to take care of him regardless. He also thought it was cowardly that his former wife would wait until she was no longer around to share the truth with him. “So she thought she’d rather drop this bomb on my life when I could no longer confront her about it,” the man wrote. “Now that my son would only have one parent looking out for him, and she’d have no idea how I would even react. Maybe I should not have got the paternity test done. Maybe it might be better to live in ignorance. But I just had to know.” The paternity test result The man took the paternity test and learned he wasn’t the child’s biological father. “I’m devastated. This doesn’t change how I feel about my son,” he wrote. “He’s my whole world and he’s innocent. But boy, does it hurt. There’s so much going on in my head right now. I haven’t stopped crying. Thank god my son is at my parents’ place for the day. I’d hate for him to see me like this.” Facing a pain nearly too much for him to bear, the only outlet he had at the moment was reaching out to Reddit to find some solace. “I just needed to let this all out. Don’t have it in me to tell anyone in my life about this right now,” he wrote.

Your feelings are valid. Each and everyone,” – femunndsmarka “He is going to find out the truth one day. Imagine how much more he will love you knowing you didn’t leave him, even though he wasn’t yours.” – ImNotGoodatThis6969 “As an adopted child, I just want to thank you on behalf of your son. I deeply believe it changes nothing, family is not about blood, its about who you love, want to have by your side, and care for the most. Sending hugs, strength and gratitude.” – Mariuuq The father at the heart of this story is understandably devastated because his life was upended almost overnight. But the hope in the story is that his trials also taught him a powerful truth: his love for his son goes much deeper than blood. This article originally appeared three years ago. It has been updated.
